7 0

G(x) = 2[f(x)]^2 - 1 g(x) = 2[2x + 1]^2 - 1 g(x) = 2[ $4 x^{2}$ 4x+1] - 1 g(x) = $4 x^{2} +4x+1$ - 1 g(x) = $4 x^{2} +4x$

Tina has 1/4 of a cake. He divides it between his 6 friends. How much of the whole cake will each friend get?

klemol [59]

As Tina only has 1/4 of a cake. For simplicity sake we can do the calculation with a whole cake and then multiply by four!

First it is stated that cake is divided into six pieces, giving us our first number.
So,

6 x 4 = 24

This means that each friend will get 1/24th of the whole cake.
