Higher Order Thinking a carpenter plans to extend the length of rectangular desk by 7 feet. Let x represent the desk's original

abruzzese [7]

Answer:

d. 9x + 63 and 63 square feet

Step-by-step explanation:

Given

Original

$Length = x$

$Width = 9$

Extended

$Length = x + 7$

$Width = 9$

$Area = 9(x + 7)$

Required

Determine an expression and the value of the extended area

First, we calculate the area of the original desk

$A_1 = x * 9$

$A_1 = 9x$

From the given parameters, we have:

$Area = 9(x + 7)$ --- area of the new surface

Open bracket

$Area = 9x + 63$

The area of the new surface is the summation of the area of the original desk and the area of the extended portion (E)

So:

$Area = A_1 + E$

Make E the subject

$E= Area - A_1$

$E= 9x + 63 - 9x$

$E= 63$

Hence, the area of the extended portion is 63
