Question

an expression for the area of the rectangle shown below. -4x + 2 7

Explanation:

Step1: Recall area formula

The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Identify length and width

Here, the length $l=-4x + 2$ and the width $w = 7$.

Step3: Calculate the area

$A=7\times(-4x + 2)=-28x+14$.

Answer:

$-28x + 14$
