Step-by-step explanation:
Answer: he needs to buy 578.5 yard² of Sod.
Step-by-step explanation:
Assuming the lawn is square shaped, the formula for determining the area of a square is
Area = length²
If the length of each side of the lawn is 24 1/2 = 24.5 ft
Area of the lawn = 24.5² = 600.25yard²
The area of the pool house is 16yard²
The area of the side walk is
3 × 1 = 3 yard²
The length of the pool is 7 1/2 = 7.5yards
The width of the pool is 2 1/2 = 2.5 yards. Therefore,
Area of pool = 7.5 × 2.5 = 18.75 yard²
Therefore, the amount of Sod that he needs to buy is
600.25 - (3 + 18.75) = 600.25 - 21.75
= 578.5 yard²
Answer:
The number is 7
Step-by-step explanation:
A number (x) multiplied by 8 = 8x divided by four gives;
8x ÷ 4 = 2x
The answer is seven more than the number i.e
2x = x + 7
2x - x = 7 , x = 7
So the number is 7.
Answer:
9x +2
Step-by-step explanation:
f(x) = 3x+ 10x
g(x) = 4x - 2,
(f - g)(x)= 3x+10x - (4x-2)
Distribute the minus sign
= 3x+10x -4x+2
Combine like terms
= 9x +2
