A picture is 5 inches by 7 inches. There is a frame around the picture that is of uniform width. The area of the frame and the picture combined is 72 in? How wide is the picture frame?
Formulate an equation that you would use to solve for x, the width of the picture frame.
es :)
A)
(5 + x)(7 + x) = 72
B)
(5 - x)(7 - x) = 72
C)
(5 + 2x)(7 + 2x) = 72
D)
(5 - 2x)(7 - 2x) = 72

is there any photos or whatever?

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

=240

=48
