[f(x) = 3x + 2
g(x) = x2
find gf(5)
find fg(x)

gf(5) = 289.

fg(x) = 3x^2 + 2.

Step-by-step explanation:

f(5) =  3(5) + 2 = 17

So gf(5) = 17^2 = 289.

fg(x) =  3(x^2) + 2   (we replace the x in f(x) by g(x)).

= 3x^2 + 2.  

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
