The answer is c ...use the distrubutive property to check it
Per 1 yard the cost would be $0.38. Not sure what unit you need it in, but thats the answer in yards.
The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
– – – – (1)
– – – – (2)
To find the solutions to f(x) = 64.
Equate equation (1) and (2), we get

Subtract 15 from both sides of the equation.



Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
Answer:
The expression means that X+20
