Answer:
C) x = ½
Step-by-step explanation:
Using the <em>Distributive Property</em> and combining like-terms will give you this:
-12 + 10x = 2x - 8
- 10x -10x
--------------------
-12 = -8x - 8
+ 8 +8
-------------
-4 = -8x [Divide by -8]
½ = x

Answer:
42
Step-by-step explanation:
g(4) = 2x^2+5
= 2(4)^2+5
= 2(16)+5
= 32+5
= 37
f(g(4)) = 21+3sqrt(x+12)
= 21+3sqrt(37+12)
= 21+3sqrt(49)
= 21+3(7)
= 21+21
= 42
