Answer:
C) 5
Explanation:
![(6x²+19x+10)/(2x+5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ylya02uufrcmvy1jlww7rqjw05l1qte5lp.png)
=
![(3x(2x+5)+2(2x+5))/(2x+5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mz8unzx97l5ptz5z17krpdygvw72ie7tw9.png)
=
![((2x+5)(3x+2))/(2x+5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/eh5gefcumbyhtiu0yhs6utr112djbevacp.png)
= 3x+2
which means that if they want us to find what ax+b is, you can figure out that ax+b is similar to 3x+2 and plug in what they want us to solve for, a+b.
ax+b=3x+2 (hence 3=a and 2=b)
wants: a+b
answer: 3+2= 5
hope this helps! :)
