I need help what is 1+1
I am having a mental breakdown here

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

What is the ratio for the surface areas of the cones shown below, given that they are similar and that the ratio of their radil and altitudes is 4: 3? 23

I’m still confused on how to work the percentages
