Your answer would be f(0)=7.07
1. Substitute 0 into x.
2(0)^2+5√(0+2)
2. Simplify
2(0)+5√2
0+5√2
5√2
7.07
This is the simplest and rounded form, therefore, it is the answer to your question.
5x+8=-27
8 more means addition. -27 would be total. 5 times the number ( in this case x) would mean multiplication.
