Carl's new car gets 27 miles per gallon. What is the equation that represents y, the total miles driven on x gallons of gas?x = 27y
y = 27 + x
x = 27 + y
y = 27x

Answers

Answer 1
Answer:

Answer:

The total miles driven equation is y=27x

Step-by-step explanation:

Given:

Number of gallons of gas is x.

Total miles driven is y.

Carl's new car gets 27 miles per gallon.

Hence to calculate total miles driven we need to multiply 27 with number of gallons of gas.

Hence the equation becomes.

y=27x

A+15 = -8 I need help solving this

Answers

Solutions 

Solution

1) Subtract 15 from both sides

A=−8−15

2) Simplify −8−15 to −23

A=−23 

Check your work 

A+15=−8

1) Let A=−23

−23+15=−8

2) Simplify −23+15 to −8

−8=−8 

The answer is correct 
ok so basically to solve for a do the inverse(opposite) of 15 which is to subtract 15 from both sides so that results in -23

Which of the following is the correct factorization of the polynomial below?x3 -12
O A. (x+3)(x-4)
O B. (x-3)(x + 4)
O C. (x+3)(x2 - 4x + 4)
O D. The polynomial is irreducible.​

Answers

Answer: The polynomial is irreducible

Step-by-step explanation:

There is nothing we can subtract between x3-12

For example: you are trying to find the polynomial of x4-6

Options:

A. (x+4)(x-6)

B. (x+1+3)(x-6)

C. None the polynomial is irreducible.

You would chose C because there is no subtraction sign in between the parentheses. If you would choose a right answer, you would rewrite it as:

(x+4)-(6)

A right triangle has an area of 50 square inches. If the triangle is an isosceles triangle, what are the lengths of the legs of the triangle?

Answers

area=1/2bh
50=1/2bh
times 2
100=bh
solve for b
divide by h
100/h=b
we hav to make a drawing
since it is isocoleese
h=b
100=b^2=h^2
h=b=10
answer is 10 inches
10in and 10in, because 10x10=100, and 100/2=50
