Answer:
x = ±sqrt(2)
Step-by-step explanation:
8x^2 - 5 = 11
Add 5 to each side
8x^2 - 5+5 = 11+5
8x^2 = 16
Divide each side by 8
8x^2 = 16/8
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)

The answer would be 15 because if 10 is the width after enlarging the photo graph you would do 10 divided by 3 which is 3.3333333. Then you would do 3.3333333 times 4.5 which is 15!
