<u>Answer:</u>
<h3>(

) x (

) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
(
) x (
)
The area = 
So, the equation to find the area of such a rectangle would be:-
(
) x (
)
Solve your equation step-by-step.
x2+4x+4=0
Factor left side of equation.
(x+2)(x+2)=0
Set factors equal to 0.
x+2=0
or
x+2=0
x=−2
Yes you can and you do that by multiplying $42×1.30=54.60 and then $54.60×1.25=68.25
