Answer:

10x

Step-by-step explanation:

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

then you multiply them both 5*2x

and you get 10x
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
