The stright side of the hula hoop would be 2 inches

if you solve those equations for "c" and "d" respectively, you'd get, well the Q point of c,d
You didn’t send an image so i’m just going to guess. I will guess 2/5
Answer:.66
Step-by-step explanation:
You divide 8 and 12
Your post would be clearer if you'd please put each function on its own line:
f(x) = (x + 4)2 + 4
f(x) = –(x + 4)2 + 4
f(x) = (x – 4)2 – 4
f(x) = –(x – 4)2 – 4
Also, use "^2" to denote "squaring." x2 has no meaning.
f(x) = (x + 4)^2 + 4 has a parabolic graph with vertex (-4,4). It increases steadily once x is greater than -4. Reject this choice.
f(x) = –(x + 4)^2 + 4 has a parab. graph with vertex (-4,4) also. It decreases steadily once x is greaster than -4. This is the answer.
Analyze the other 2 possible answers in the same way, please.
