Miriam reduced a square photo by cutting 3 inches away from the length and the width so it will fit in her photo album. The area of the reduced photo is 64 square inches. In the equation (x – 3)2 = 64, x represents the side measure of the original photo.

What were the dimensions of the original photo?

11 inches by 11 inches
5 inches by 5 inches
3 + 4 StartRoot 2 EndRoot inches by 3 + 4 StartRoot 2 EndRoot inches
3 4 StartRoot 2 EndRoot inches by 3 4 StartRoot 2 EndRoot inches

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
