What is the value of 9(n+2)−5n for n=14?
3
9
10
19

If you want to know the value of a  function, you need to substitute the variable (here n) for the value:

so in the function

9(n+2)−5n

we substitute n with 14:

9(14+2)−5*14

first calculate the inside of the bracket:


9*16−5*14

9 times 16 is 144

144-5*14

5*14 is 70, so we have

144-70=74

so the answer should actually be 74!
