Question

Someone help me please

Answer 1

Would be 10x as they tell you what f(x) is and what g(x) is they then ask you to multiply and as these values are equal to 5 and 2x when multiplying the numbers are collected to 10 and x can’t be simplified further so it would stay as x making the answer 10x

Answer 2

10x

Explanation:

you substitue f(x) with 5 and g(x) with 2x

then you multiply them both 5*2x

and you get 10x
