Pulling out like terms
4.1 Pull out like factors :
3x3 - 9x2 - 12x = 3x • (x2 - 3x - 4)
Trying to factor by splitting the middle term
4.2 Factoring x2 - 3x - 4
The first term is, x2 its coefficient is 1 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
x2 - 4x + 1x - 4
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-4)
Add up the last 2 terms, pulling out common factors :
1 • (x-4)
Step-5 : Add up the four terms of step 4 :
(x+1) • (x-4)
Which is the desired factorization
Equation at the end of step
4
:
3x • (x + 1) • (x - 4) = 0

Theory - Roots of a product
5.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

what is half of 2^6?????
Need this asap so if you see this and are willing to help me please do
Answer:
32
Step-by-step explanation:
2 to the 6th power is also 2 x 2 x 2 x 2 x 2 x 2 which equals 64 so then you multiply it by .5 (half) to get 32 :)
Answer:
32
Step-by-step explanation:

Answer:
45
Step-by-step explanation:
So you have the equation:
(3x - 5) ^(x) - 19
and the value x = 3,
so just substitute in and simplify:
(3*3 - 5) ^ (3) - 19
(9 - 5)^(3) - 19
(4)^(3) - 19
64 - 19

The table and graph represent two different bus tours,
showing the cost as a linear function of the number of
people in the group.
Which description best compares the two functions?
Tour 1
Tour 2
People
Cost ($)

65
75
Number of People
The functions have the same
initial value.
The functions have the same
rate of change.
The rate of change for Tour
1 is greater.
Both functions are the same.
Answer: The functions have the same initial value
Step-by-step explanation: I say this because "Tour 1" is a linear funtion. I subtracted 45 from 55 and got 10, this happened for all the numbers on the table. On the other hand, When observing the graph it shows the initial point between 40 and 30. I estimated and got 35. When I went to check my answer, I subtracted 35 from 45 and got 10. Therefore, 35 is the initial value for both the graph and the chart.
Answer:
the function have the same initial value

The price of a gallon of unleaded gas has risen to $2.86 today. Yesterday's price was $2.81. Find the percentage increase. Round your answer to the nearest tenth of a percent.
Answer:
1.8%
Step-by-step explanation:
2.86-2.81 = .05 (find the difference between the two numbers)
2.81 / .05= .017 (divide the original number)
Multiply 100 to get a percentage

A formula for finding P, the perimeter of a rectangle, is P = 2l + 2w, where l is the length of the rectangle, and w is its width.
What is P when l = 10 centimeters and w = 5 centimeters?
Answer:
Perimeter is 30
Step-by-step explanation:
The formula is
P=2(l+w)
Answer:
P is 30cm
Step-by-step explanation:
Let's transform it into an expression:
P = 2w + l2
P = (5×2) + (10×2)
P = 10 + 20 = 30 cm

First I multiplied.
15.24 x 1.64 = 24.9936
Then I convert my answer to British pounds.
24.9936 = 19.334 British Pound Sterling
Answer:
1.36
Step-by-step explanation:
15.24 = 8.44 + 5x
subtract 8.44 from both sides
6.80 = 5x

x = 1.36
Which of the following pairs of triangles can be proven congruent by AAS?
A. (Image 1)
B. (Image 2)

Answer:
D is the correct
Step-by-step explanation:
The pairs of triangles that can be proven to be congruent by the AAS Congruence Theorem is: D. image 4.
What is the AAS Congruence Theorem?The AAS congruence theorem states hat two triangles can be proven to be congruent triangles if two angles and a non-included side of one triangle are congruent to corresponding two angles and a non-included side of the other triangle.
In image 4, ΔABC and ΔWXY has the following:
two pairs of congruent angles - ∠A ≅ ∠W and ∠C ≅ ∠Ya pair of congruent non-included sides - AB ≅ WXTherefore, the pairs of triangles that can be proven to be congruent by the AAS Congruence Theorem is: D. image 4.

ꜱᴏʟᴠᴇ (-9x-3)+(-3+2x)
[tex] \LARGE{ \underline{ \pink{ \bf{Required \: answer:}}}}[/tex]
I think, Here solving the equation means simplifying the equation which will include steps like expanding the parentheses etc.
GiveN:
(-9x + 3) + (-3 + 2x)Since we have add the terms inside the parentheses, the signs will remain as usual.
⇛ -9x + 3 - 3 + 2x
Combining the like terms and constant terms,
⇛ -9x + 2x + 3 - 3
This can be written as,
⇛ -7x + 0
⇛ -7x
Thus, On solving the equation we got -7x.
Answer:
−7x−6
Explanation:
(−9x−3)+(−3+2x)
Subtract 3 from −3 to get −6.
−9x−6+2x
Combine −9x and 2x to get −7x.
−7x−6
