What is the value of 9(n+2)−5n for n=14?<br> 3<br> 9<br> 10<br> 19
Murrr4er [49]
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:

<span>9(14+2)−5*14

first calculate the inside of the bracket:

</span>
<span>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!

Perhaps you mistyped the questions? can you check it again, please?
