What is the answer to this question

c. 4

Step-by-step explanation:

The area of a rectangle is base times height. The base here is x, and the height is x*5. So you have the equation:

x(x+5)=36

x^2+5x=36

x^2+5x-36=0

(x+9)(x-4)=0

x=-9,4

However, distance cannot be negative, so x must equal 4.

Although, keep in mind, you could have just done guess and check and it wouldnt have taken that long.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

answer:

your answer is: c. 196 7/8 in^3.
