5

2

Step-by-step explanation:

18 + 17 + 3 = 28

30 - 28 = 2

if 18 take Social Studies and 17 take Technical  Drawing amd 3 take neither, we can assume the 2 left over are the pupils that take both

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
