Answer:
(g◦f)(x) = 2x +1
Step-by-step explanation:
(g◦f)(x) = g(f(x)) = g(2x -1) = (2x -1) +2
(g◦f)(x) = 2x +1
__
Substitute f(x) for the argument in the function g(x) and simplify.
367 is the best answer I came up with
Answer:
x = 6
Step-by-step explanation:
5 sides all the same length
s = 22.5/5
s = 4.5
--------------------
x - 1.5 = 4.5
Add 1.5 to both sides
x = 6
You can do 5+5+10, 6+6+8, 9+9+2, 4+4+12, 3+3+14, 2+2+16, 1+1+18. I believe these are all of them, so there are 7 ways.
