Answer:
f(g(3)) = 56
g(f(3)) = 25
Step-by-step explanation:
fog = f(2x+1)
f(2x+1) = (2x+1)^2 + 2x+1
(2x+1)^2 + 2x+1 = 4x^2+6x+2
f(g(x)) = 4x^2+6x+2
f(g(3)) = 4(3)^2+6(3)+2
f(g(3)) = 56
gof = g(x^2+x)
g(x^2+x) = 2(x^2+x)+1
2(x^2+x)+1 = 2x^2 + 2x + 1
g(f(x)) = 2x^2 + 2x + 1
g(f(3)) = 2(3)^2 + 2(3) + 1
g(f(3)) = 25
I believe that the answer to the question provided above is that <span>the maximum total area that 450 cm of string can enclose if it is used to form the perimeters of two is area = 12 656.25 sqr cm. 450/4 = x . x^2 = area</span>

Answer:
125 units^3
Step-by-step explanation:
Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.
You then divide the sides by 2 because the question says the second cubes sides are half the size
5*5*5 = 125
