Answer:
f[g(x)] = 6x + 47
Step-by-step explanation:
The expression f[g(x)] represents a composite function. You need to plug the function g(x) into the "x" value of the f(x) function. Then, you can simplify.
f(x) = 6x + 11 g(x) = x + 6
f[g(x)] <----- Composition expression
f[g(x)] = 6(x + 6) + 11 <----- Plug g(x) into x
f[g(x)] = 6x + 36 + 11 <----- Multiply terms in parentheses by 6
f[g(x)] = 6x + 47 <----- Add 36 and 11
First we need to know the actual answer, which would be 14, knowing this, we can split up 84 into smaller pieces that are easier to divide, 42 would be easier, so distributive property would be (42 divided by 6)+(42 divided by 6), 6x7=42, 7x2=14, so yea i hope this helped
