$35\%$

Step-by-step explanation:

For this exercise you need to use the following formula:

$\%increase=\frac{New\ value-Old\ value}{Old\ value}*100$

According to the exercise, the number of kids in a robotics club grew from 23 to 31; then you can identify that:

$New\ value=31\\\\Old\ value=23$

Knowing these values, you can substitute them into the equation and then evaluate, in order to find the percent increase in the number of kids in the club. Then:

$\%increase=\frac{31-23}{23}*100\\\\\%increase=34.78\%$

Rounding it to the nearest whole percent:

$\%increase=35\%$

(g + f)(8) =133

Step-by-step explanation:

Given

g(n) = 3n - 5

f(n) = n^2 + 50

Required

(g + f)(8)

This is calculated as:

(g + f)(n) =g(n) + f(n)

So, we have:

(g + f)(n) =3n - 5 + n^2 +50

Substitute 8 for n

(g + f)(8) =3*8 - 5 + 8^2 +50

(g + f)(8) =24 - 5 + 64 +50

(g + f)(8) =133
