Step-by-step explanation:
Pretend if Mr. Yasin didn't pay for the 3rd box, find out how much he had left after paying for the first 2 boxes.
9.43 - 3.99 - 2.97 = 2.47

Answer:
Step-by-step explanation:
Given
x - 
= 9 ← square both sides
(x - )² = 9²
x² - 2 + 
= 81 ( add 2 to both sides )
x² + = 83
Now
(x + )² = x² + + 2, thus
x² + = 83 + 2 = 85
(x + )²= 85 ( take the square root of both sides)
x + =
