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?
Answer:
11 inches
Step-by-step explanation:
Take the square root and add 3.
(x -3)² = 64
x -3 = √64 = 8
x = 8 +3 = 11
The original photo was 11 inches on a side.
