Answer:
1.1 gallons of paint
Step-by-step explanation:
The wall measures;
21 foot by 17 foot
Thus, area of wall = 21 × 17 = 357 ft²
Circular area has a radius of 5 ft.
Thus;
Area of circle = πr² = π × 5² = 78.54 ft²
Total area covered = 357 + 78.54 = 435.54 ft² ≈ 436 ft²
A gallon of paint can cover 400 ft²
Thus gallons Muhammad would need = 436/400 = 1.09 gallons ≈ 1.1 gallons
First multiple everything in the parentheses by
3
3 (2x+3)-6=
3(2x)+3(3)-6=
6x+9-6
then add together like terms
6x+9-6=
6x+3
so 6x+3 is your answer
1/3 times area of base times height
1/3 x (11x7) x 8
1/3 x 77 x 8
Answer is approximately 205.3

Brainiest if I'm correct, thanks!</h2>
Answer:
7x² meters
Step-by-step explanation:
Area = length × width
35x³ = length × 5x
length = 7x²
