Answer:
289feet²
Step-by-step explanation:
Area of a rectangle = length x breadth
area of a square = length²
area of the yard that is not covered by the hot tub and fire pit =
Area of the yard - (area of the hot tub + area of the fire pit)
Area of the yard = 20 feet² = 400 feet²
area of the hot tub = 6 feet² x 8 feet² = 48 feet²
area of the fire pit = 7 feet² x 9 feet² = 63 feet²
400 - (48 + 63) = 289 feet²
Answer:
y=x xy+2
Step-by-step explanation:
Let say the number = x
double my number and add eight, I get my number plus twelve
double x and add eight, I get x plus twelve
2x + 8 = x + 12 (subtract x from each side)
2x - x + 8 = 12
x + 8 = 12 (subtract 8 from each side)
x = 12 - 8
x = 4
Your number is 4
