The one wall would be 13 feet long.
13+13+13+13= 52 feet.
Just guess and check. For example, for the first on the left, I guessed 3 to begin with. 3 + 3 + 3 = 9, but 10 + 3 = 13, so 3 is not the answer. I then guessed 5. 5 + 5 + 5= 15, and 10 + 5= 15, so star = 5.
Answer:
4x^2 -8
Step-by-step explanation:
f(x)=3x^2-9
g(x)=x^2+1
(f+g)(x)=3x^2-9 +x^2+1
Combine like terms
= 4x^2 -8
Answer:
The domain is all real numbers except x=3
Step-by-step explanation:
Assuming you mean
f(x) = 1/(x-3)
The domain is all numbers that x can take
This function is define except when the denominator goes to zero
x-3 cannot be zero
x cannot be 3
The domain is all real numbers except x=3
