Question

A rectangle has a length of 2x + 1 and a width

Answer 1

Answer:

H

Step-by-step explanation:

The rectangle has a length of (2x + 1) and a width of (5x - 4).

And we want to select the expression that represents the rectangle's area.

Recall that a rectangle's area is simply its length multiplied by its width. Thus:

$A=(2x+1)(5x-4)$

Expand by distributing:

$A=(2x+1)(5x)+(2x+1)(-4)$

Distribute:

$A=(10x^2+5x)+(-8x-4)$

Simplify:

$A=10x^2-3x-4$

Hence, our answer is H.
