Question

The area of the rectangle shown is 32x^2 + 12 If width can be represented by 4x, write an expression to represent the length of the rectangle

Answer 1

L=(8x^2+3)/x

Explanation:

The area of a rectangle is length time width.

A=LW

In this case,

A=32x^2+12

W=4x

Solve for L

L=A/W

Substitute

L=(32x^2+12)/4x

L=(8x^2+3)/x
