P= 2(x+1) + 3(x-8)
= 2x+2+3x-24
= 5x-22
Answer:
Below.
Step-by-step explanation:
7(x + 2) = 91
Distribute the 7 over the parentheses:
7x + 14 = 91
Subtract 14 from both sides of the equation:
7x = 91 - 14
7x = 77
x = 77/7 = 11.
Answer:
5.6 ft
Step-by-step explanation:
Answer:
L = 22 ft
Step-by-step explanation:
Let L and W represent the length and width respectively.
L = 4W, or W = L/4. Use W = L/4 because we want to solve for W, not for L.
Area of a rectangle: A = L · W
Here, A = L · L/4 = 121 ft²
Mult. both terms by 4 removes the fraction:
L² = 484
Finding the square root of this result: L = 22
The length of the rect. is 22 ft.
