 Step-by-step Solution

 

1

Expand the integral $\int_{2}^{4}\left(9x+4\right)dx$ into $2$ integrals using the sum rule for integrals, to then solve each integral separately

$\int_{2}^{4}9xdx+\int_{2}^{4}4dx$

 

2

The integral $\int_{2}^{4}9xdx$ results in: $54$

$54$

3

The integral $\int_{2}^{4}4dx$ results in: $8$

$8$

 

4

Gather the results of all integrals

$54+8$

 

5

Add the values $54$ and $8$

$62$
