Answer:
16 square feet was left over after he cut out the windows
Step-by-step explanation:
The formula of the area of a rectangle is A = l × w, where
- l is the length of the rectangle
- w is the width of the rectangle
∵ The dimensions of each window are 8-foot by 4-foot
∴ l = 8 feet and w = 4 feet
→ By using the rule above find the area of each window
∵ A = 8 × 4
∴ A = 32 feet²
∴ The area of each window = 32 feet²
∵ He cut 2 windows
∴ The area of the 2 windows = 2 × 32
∴ The area of the 2 windows = 64 feet²
∵ The area of the wall is 80 feet²
→ To find the area of the wall left, subtract the area of the windows from
the area of the wall
∵ The area left = 80 - 64
∴ The area left = 16 feet²
∴ 16 square feet was left over after he cut out the windows
Answer:
75
Step-by-step explanation:
5(6+9)
Times the five by the numbers in the bracket

= 75
The answer is 2 well that’s what I got
20-(3^2)(2)/6= 20-(9)(2)/6= 20-18/6=
20-3= 17 ------> 17 is your simplified answer
