Answer:
Step-by-step explanation:
4x³ - 8x² - 12x = 4x ( x² - 2x - 3)
= 4x (x² + x - 3x - 3*1)
= 4x [ x(x + 1) - 3(x +1)]
= 4x [ (x +1) (x - 3)]
= 4x (x + 1)(x-3)
Answer:4x^3 -8x^2- 12x
Taking common4 x
4X(x²-2x-3)
Doing middle term factorization
4x(x²-3x+x-3)
4x(x(x-3)+1(x-3))
4x(x-3)(x+1) is your answer

David is an enthusiastic cyclist. He uses an app on his phone to track each of his cycling sessions below is shown some information about his last three
The required diagram is attached in the picture below :
Answer:
15.05 miles
2 :09:12
5 hours 19 minutes 18 seconds
Step-by-step explanation:
Given :
28/4/18:
Time : 1 :03 : 25
Fastest mile = 02 : 25
Distance = 15.05 miles
03/5/18:
Time : 2:06: 41
Fastest mile = 02 : 53
Distance = 28.70 miles
08/5/18:
Time : 2 :09:12
Fastest mile = 02 : 45
Distance = 26.39 miles2
1.) shortest distance cycled :
From the data:
15.05 < 26.39 < 28.70
Shortest distance cycled = 15.05 miles
The longest the cycled:
1 :03 : 25 < 2:06: 41 < 2 :09:12
Longest = 2 :09:12
Total cycling time :
1 :03 : 25 + 2:06: 41 + 2 :09:12
(1 + 2 + 2)= 5 hrs
(03 + 06+ 09) = 18 minutes
(25 + 41 + 12) = 78 seconds = 1 minute 18 seconds
18 minutes + 1 minute = 19 minutes
Total = 5 hours 19 minutes 18 seconds
Solve using the appropriate formula. Substitute 3.14 for π. Hint: Circle: A = πr2 Find the area of a circle with a radius of 4 cm.
Answer:
The area of a circle is [tex]\pir^{2}[\tex] and the radius is 4 so we have 16π and substituting 3.14 for pi we get 50.24 .

The Pythagorean Theorem is
c² = g²-6²
False
O True
O No answer text provided.
O No answer text provided.
Answer:
FalseStep-by-step explanation:
It depends on the triangle.
If a is the longest side then it's true, but usually when we talk about Pythagorean theorem we mean that c is the longest side of the right triangle. So:
c² = a² + b²I need help with this
Answer:
since k is the constant for any proportionality, simply do 48/4 since 48=y and 4=x or y/x, your constant will be equal to 12 as well as ur unit rate point since they said it is the same as your constant, your equation would be y=12x

828 square inches
1,092 square inches
О
1,400 square inches
o
2,016 square inches
о
Answer:
Step-by-step explanation:
base = 784 sq in² 28 in tall pyramid
each side of the square base = √784 also equals 28
using the Pythagorean theorem the length of each side of the pyramid from the base to the point is
(side/2)² + height² =( length of the pyramid face)²
(28/2)² + 28² = 196 + 784 = 980 = (face length)²
face length = √980 = 31.3
area of the pyramid = 4 sides × area of each face + the area of the base
= 4×[(1/2)(base)(face length)] + side²
= 4(1/2)(28)(31.3) + 784
= 2537 sq in² Not in the solution set

what is the value of z?
Answer:
3 (z = 35)
Step-by-step explanation:
(22 + 19) + 104 + z = 180° => triangle sum theorem
41 + 104 + z = 180
145 + z = 180
145 + z - 145 = 180 - 145
z = 35

Which statement best describes where the StartFraction pi Over 4 EndFraction comes from in the formula derivation? It is the ratio of the area of the square to the area of the circle from a cross section. It is the ratio of the area of the circle to the area of the square from a cross section. It is the difference of the area of the square and the area of the circle from a cross section. It is the sum of the area of the square and the area of the circle from a cross sectio
Answer:
Adding 12 to the circle area is equal to the square area.
Or
s2 = 12 + A
Where
s = side of square
A = area of circle
So
s2 = 12 + 36
s2 = 48
Solve this for s to get the side length
Of the students in the college, 60% of the students reside in the hostel and 40% of the students are day scholars. Previous year result reports that 30% of all students who stay in the hostel scored A Grade and 20% of day scholars scored A grade. At the end of the year, one student is chosen at random and found that he/she has an A grade. What is the probability that the student is a hostlier?
Answer:
9 / 13
Step-by-step explanation:
From the question :
Let :
Hostel students = h
Day students = d
Students with A grade = a
P(h) = 60% = 0.6
P(d) = 40% = 0.4
P(hostel with A grade) ; P(A / H) = 0.3
P(day with A grade) ; P(A / D) = 0.2
The probability that a student picked at random withbA grade is an hostel student is given as :
Probability of being an hostel student gun he has A :
P(H | A) = (P(A/H) * P(H)) ÷ P(A/H) * P(H) + P(A/D) * P(D))
P(H | A) = (0.3 * 0.6) ÷ ((0.3*0.6) + (0.2*0.4))
P(H | A) = 0.18 ÷ (0.18 + 0.08)
P(H | A) = 0.18 ÷ 0.26
P(H | A) = 9 / 13

Find the area of all the shapes and then add them together I believe...
Answer:
468 Square Centimeters
Step-by-step explanation:
Surface area can be calculated by adding the areas of each face on a prism:
The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468please let me know if the answer or explanation is incorrect, hope this helps :)
What inverse operations do you use to solve for b?

Answer:
I would use multiplication
Step-by-step explanation:
Multiplication is the opposite of dividing.
X^2=9 in standard form?
Answer:
±3
Step-by-step explanation:
x² = 9
Taking square root on both sides,
x = 3
Solve for x. 6x-20 4x+50
Answer: Simplifying
4x + 50 = 6x + 20
Reorder the terms:
50 + 4x = 6x + 20
Reorder the terms:
50 + 4x = 20 + 6x
Solving
50 + 4x = 20 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
50 + 4x + -6x = 20 + 6x + -6x
Combine like terms: 4x + -6x = -2x
50 + -2x = 20 + 6x + -6x
Combine like terms: 6x + -6x = 0
50 + -2x = 20 + 0
50 + -2x = 20
Add '-50' to each side of the equation.
50 + -50 + -2x = 20 + -50
Combine like terms: 50 + -50 = 0
0 + -2x = 20 + -50
-2x = 20 + -50
Combine like terms: 20 + -50 = -30
-2x = -30
Divide each side by '-2'.
x = 15
Simplifying
x = 15
She square was 10 ft by 10 ft. Suppose uses the same amount of fencing to enclose a circular area. What is the area of the circle? Use 3.14 for .
Answer:
127.41ft^2
Step-by-step explanation:
Given data
DImension of the square
10ft by 10ft
The perimeter of the square is
=10+10+10+10
=40ft
Hence the amount of the fencing of the circle is 40ft
That is the circumference is 40ft
C=2πr
solve for r
40=2*3.14*r
40=6.28r
r= 40/6.28
r=6.37 ft
Area= πr^2
Area= 3.14*6.37^2
Area= 3.14*40.5769
Area= 127.41ft^2

Look at thee isosceles triangle what angle is B?
(I am so so tired is 2 in the morning)
Answer:
m∡b = 50°
Step-by-step explanation:
this is an isosceles triangle so the other base angle also measures 65°
there are 180° in a triangle so m∡b = 180-(65+65) or 50°
What is the equation for y in the inequality -3(2y+4) < 12 - 4y?
-6y-12<12-4y

Now add 4y on both sides.
-10y<24
Divide -10.
y<-2.4

Please help me for 1 and 6.
Answer:
6=28 1=125
Step-by-step explanation:
65+59=124 180-124=56/2 equals 28 and if the question is correctly written
then both sides that you don't yet know should be 28
The answer for one if I'm correct is 125 since you add 204+31=235 then you do 360-235=125
If I'm wrong at all I'm sorry but with that how are you in math honors when I'm just in algebra 1 T_T
