Answer:
the first piece of rope would be 4 feet
Step-by-step explanation:
4 + 8 + 9 = 21
Answer:
-3
Step-by-step explanation:
Please write this as f(x) = x^2 + 4x - 12. "x^2" represents "the square of x."
f(2) is the value of this function when x = 2:
f(2) = f(2) = (2)^2 + 4(2) - 12 = 9 - 12 = -3
I think you are correct actually.
F(x) = -x² + 4
f(3) = -3² + 4
f(3) = -9 +4
f(3) = -5
