Carl is 2 yrs older than bob. Because Alan+Carl is 2 more than Alan+bob
So bob=16 and Carl is 18
16+18=34
And Alan is 24
Question 1)
Given: F(x) = 3x^2 + 1, G(x) = 2x - 3, H(x) = x
F(G(x)) = 3(2x - 3)^2 + 1
F(G(x)) =3(4x^2 - 12x + 9) + 1
F(G(x)) = 12x^2 - 36x + 27 + 1
F(G(x)) =12x^2 - 36x + 28
Question 2)
Given: F(x) = 3x^2 + 1, G(x) = 2x - 3, H(x) = x
H -1 (x) = x (inverse)
27+5= 32 total square feet.
32/4= 8 square feet per roll.
You can cross multiply
-11(-9) x *( 1)
99=1x
99=x
the answer is 99=x
