Answer:
B. 3x² -17
Step-by-step explanation:
f(x)= 3x+1
g(x)= x² -6
(f °g)(x) =f(g(x)) so plug in in f for variable x²-6
(f °g)(x) = 3(x² -6) +1 =3x² -18 +1 = 3x² -17
The "answer" is the number that 'x' must be
in order for that equation to be true.
To find it, just divide each side of the equation by 8.3 .
Then it'll say x = 5 .
y/5 = x
multiply by 5 on each sides
y = 5x
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
6
Step-by-step explanation:
The number on the right side of the equal side represents the radius, HOWEVER, it is squared, therefore you must square root it to get 6
8.8 squared + 9.5 squared = square root 12.94 rounded 12.1
