The area of a rectangle is the product of its length and width.
l=x+5 \\
w=3x-7 \\ \\
A=lw=(x+5)(3x-7)=3x^2-7x+15x-35=3x^2+8x-35 \\ \\
\boxed{f(x)=3x^2+8x-35}

Find the approximate surface-area-to-volume ratio of a bowling ball with a radius of 5 inches.
Nataly_w [17]
Surface area of a ball: 
S=4πr^2=4*π*5^2=100π

Volume of a circle:
V=4/3*π*r^3=4/3*π*125=(500/3)*π=165π

The approximate surface-area-to-volume ratio would be 1:1,5
