Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
2x²y exponit 7√6
First, calculate f(g(x))==> you plug (5x+4) in the value of x in f(x)
==>f(g(x))= 8-[10(5x+4)===>8-50x-40===>f(g(x))= -50x + 32
& f(g(-2))= -100+32 =68.
There is a mistake in your answers, it should be 68 & not 78
The answer is C
g(x) = (x+12)^2
Answer:
4 
Step-by-step explanation:
1+1=2 and 1
+ 1
=2
2+2
= 4
