Answer:
It is the total cost of the membership fee and the tire pressure check for 12 months.
Step-by-step explanation:
given data
Membership Fee: $50
Cost: $4 per car per month
Washing Cost: $10 per car per month
Tire Replacement Cost: $400 per car Tire Pressure Check Cost: $15 per month
let the total cost be y
and the number of cars be n'
and the number of months be x
the model for the situation is given as
y=50+4nx+10nx+15
from the expression above the constant term is the total cost of the membership fee and the tire pressure check for 12 months.

x^2+8x +16
x^3-64
x^2-16
(x-4)(x^2+4x+16)
(x+4)^2
(x-4)(x+4)
Answer:
x^2+8x +16 >> (x+4)^2
x^3-64 >> (x-4)(x^2+4x+16)
x^2-16 >> (x-4)(x+4)

Each polynomial is matched to its factored form. These are the correct answers. I did this on EDGE!
Polynomial is an expression that consists of indeterminates(variable) and coefficients.
What are polynomials?
Polynomial is an expression that consists of indeterminates(variable) and coefficients, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
To know which polynomial to match, solve the factors.
A.) (x-4)(x²+4x+16)
[tex](x-4)(x^2+4x+16)\\\\=x(x^2+4x+16)-4(x^2+4x+16)\\\\= x^3 + 4x^2 + 16x - 4x^2-16x-64\\\\=x^3 -64[/tex]
Hence, (x-4)(x²+4x+16) will match x³-64.
B.) (x+4)²
[tex](x+4)^2\\\\= x^2+8x+16\\[/tex]
Hence, (x+4)² will match x²+8x+16.
C.) (x-4)(x+4)
[tex](x-4)(x+4)\\\\ = x^2-16[/tex]
Hence, (x-4)(x+4) will match x²-16.

Answer:
36 in.
Step-by-step explanation:
the perimeter of the square is 4s and the perimeter of the triangle is 3(s+3).
since the perimeters are the same you can set them equal to each other and solve.
you should get s=9
substitute 9 into the square perimeter equation to get 36 in.

Ut of a group of 145 students that were surveyed about sports, 31 said they play basketball and 59 said they play soccer. 18 of the students who said they play basketball said they also play soccer. If a student is chosen at random, find the probability.
Answer:
0.5806
Step-by-step explanation:
Out of a group of 145 students that were surveyed about sports, 31 said they play basketball and 59 said they play soccer. 18 of the students who said they play basketball said they also play soccer. If a student is chosen at random, find the probability. P (Soccer |Basketball).
Solution:
P(soccer) = number of students playing soccer/ total number of students.
P(soccer) = 59/145
P(basketball) = number of students playing basketball/ total number of students.
P(basketball) = 31/145
P(soccer and basketball) = number of students playing soccer and basketball/ total number of students.
P(soccer and basketball) = 18/145
From Bayes theorem:
P(A | B) = P(A ∩ B) / P(B)
Hence:
[tex]P(soccer|basketball)=\frac{P(soccer\cap baketball)}{P(basketball)}=\frac{\frac{18}{145} }{\frac{31}{145} } =0.5806[/tex]

Lsat month, harri drove 850 miles in his car. his car's fuel consumption is 45.6 miles per gallon. petrol cost £1.09 per litre. given that 8pints = 1gallon, work out how much Harri spent on fuel last month. You must show working out.
Answer:
£76.904
Step-by-step explanation:
Lsat month, harri drove 850 miles in his car. his car's fuel consumption is 45.6 miles per gallon. petrol cost £1.09 per litre. given that 8pints = 1gallon, work out how much Harri spent on fuel last month. You must show working out.
a) 45.6 miles per gallon
45.6 miles = 1 gallon
850 miles = x
Cross Multiply
x = 850/45.6
x = 18.640350877 gallons
b) 8pints = 1gallon,
8 pints = 3.785 litres
1 gallon = 3.785 litree
18.640350877 gallons = y
Cross Multiply
18.640350877 litres × 3.785
= 70.5537280694 gallons
c) 1 litres = £1.09
70.5537280694 litres = z
Cross Multiply
z = 70.5537280694 × £ 1.09
z = £76.9035635957
Approximately = £76.904

Answer:
discriminant: -232 complex solutionsStep-by-step explanation:
Compare the equations ...
ax² +bx +c = 0
x² -x +6 = 0
and you can see that the values of a, b, c are ...
a = 1, b = -1, c = 6
Putting these values into the expression for the discriminant, ...
d = b² -4ac
we have ...
d = (-1)² -4(1)(6) = 1 -24 = -23
The discriminant is -23.
__
The interpretation of the discriminant is ...
negative -- 2 complex solutions
zero -- one real solution
positive -- 2 real solutions
Here, the discriminant is negative, so ...
The equation has 2 complex solutions.

One pipe can fill a tank in 8 minutes. A second can fill it in 12 minutes, and a third can fill it in 24 minutes. If the tank is empty, how long will it take the three pipes, operating together, to fill it?
Answer:
This is a trick answer but the answer is 24 minutes
Step-by-step explanation:
They have already added up the time and its 24 if you read 1 is 8 the second is 12 and 3 pipes are 24
Also lemme get brainlist
Answer:
4.8 min (4 min 48 seconds)
Step-by-step explanation:
In one minute:
Pipe A fills the tank 1/8th full
Pipe B fills the tank 1/12 full
Pipe C fills the tank 1/24th full
1/8 + 1/12 + 1/24 = 5/24
So the the at which they will fill the tank is 24/5,
or 4.8 minutes (4 minutes 48 seconds)

When the expression x^2 + bx - 24 is factored completely, the difference of the factors is 11. Find both factors if it is known that b is negative.
write the steps on the paper pleaseeee
i need it asap
Answer:
The two factors are (x + 3) and (x - 8)
Step-by-step explanation:
The given function is x² + b·x - 24
The difference between the factors = 11
The sign of coefficient b = Negative
Therefore, we have;
The factors as (x - c) and (x + d)
-b = d - c...(1)
d × (-c) = -24...(2)
(x + d) - (x - c) = 11
Which gives;
x + d - x + c = 11
∴ d + c = 11...(3)
From equation (3), we have;
d = -24(-c) = 24/c
d = 24/c
Substituting the value of d in equation (3) gives;
d + c = 24/c + c = 11
24/c + c = 11
∴ c² + 24 = 11·c
c² + 24 - 11·c = 0
c² - 11·c + 24 = 0
(c - 8)·(c - 3) = 0
c = 8 or 3
From d + c = 11, we have, d = 3 or 8
Given that -b = d - c, therefore c > d and c = 8, d = 3
Therefore, the two factors are (x - 8) and (x + 3).

(0,-4) , (8,4) writing equations in slope intercept form write an equation of each line that passes through the given points answers please
Answer:
y = x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (8, 4)
m = [tex]\frac{4+4}{8-0}[/tex] = [tex]\frac{8}{8}[/tex] = 1
The line crosses the y- axis at (0, - 4 ) ⇒ c = - 4
y = x - 4 ← equation of line
