5 because you subtract 15x and bring it to 3x^2 and get 3x^2-15x=0. Then take out the gcf and you get 3x(x-5)=0. Since it can't be 0, x-5=0 , the answer is 5.

Enrico is designing a rectangular board for a game. He wants the ratio of the length to the

Aleks [24]

Answer:

$A(x)=\frac{6}{5}x^2$

Step-by-step explanation:

Let

y ----> the length of the board

x ----> the width of the board

we know that

$\frac{y}{x}=\frac{6}{5}$

$y=\frac{6}{5}x$ ----> equation A

The area of the board is

$A=xy$ ----> equation B

substitute equation A in equation B

$A=x(\frac{6}{5}x)$

$A(x)=\frac{6}{5}x^2$
