Error Analysis A gardener plans to extend the length of a rectangular garden by 7 feet. Letx represent the garden's original length. The expression 9(x + 7) represents the area of the garden, where 9 is the width, in feet, and (x + 7) represents the extended length, in feet, of the garden When asked for the area of the extended portion, the gardener incorrectly said it was 16 square feet. Expand the expression to find the area of the extension.​

Sagot :

Answer:

9(x+7)

Distribute the 9 by multiplying it to x and 7

9x+63

The area of the extension is 63.

The gardener added 9 and 7 instead of multiplying.
