√4=2, and √45=√(9*5)=√9 *√5=3√5
so you have 2/(3√5)
Multiply both top and bottom by √5 to eliminate the √ in the denominator:
(2√5)/15 is the final answer.

Please help on my hw, I'm not feeling good, and can't concentrate
sergiy2304 [10]

Answer:

Solution given:

f(x)=x²

g(x)=x+5

h(x)=4x-6

now

23:

(fog)(x)=f(g(x))=f(x+5)=(x+5)²=x²+10x+25

24:

(gof)(x)=g(f(x))=g(x²)=x²+5

25:

(foh)(x)=f(h(x))=f(4x-6)=(4x-6)²=16x²-48x+36

26:

(hof)(x)=h(f(x))=h(x²)=4x²-6

27;

(goh)(x)=g(h(x))=g(4x-6)=4x-6+5=4x-1

28:

(hog)(x)=h(g(x))=h(x+5)=4(x+5)-6=4x+20-6=4x-14
