Answer:
A = 4a² - 4ab + b²
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length ) , so
A = (2a - b)² ← expand using FOIL
= (2a)² - 2ab - 2ab + (- b)²
= 4a² - 4ab + b²
Answer: 7 hours
Explanation: We can use the equation 93=9h+30 to represent the problem.
When we solve for h with (93-30)/9, we get 7 hours.
