1. Given f%28x%29=3x%2B8 and g%28x%29=6x%2B6
then what is %28f-g%29%28-1%29 ?
%28f-g%29%28x%29=3x%2B8-%286x%2B6%29
%28f-g%29%28x%29=3x%2B8-6x-6
%28f-g%29%28x%29=-3x%2B2
then,
%28f-g%29%28-1%29=-3%28-1%29%2B2
%28f-g%29%28-1%29=3%2B2
%28f-g%29%28-1%29=5

2. Simplify the radicals


so, (A,B)= (72,4)

3. Solve the following radical equation sqrt%282x%2B3%29=13... guess you have that
sqrt%282x%2B3%29=13
%28sqrt%282x%2B3%29%29%5E2=13%5E2
2x%2B3=169
2x=169-3
2x=166
x=166%2F2
x=83
answer is:
a. x+=+83
