Add each pair of monomials and match it to the correct sum.

tiles
-15u3 + 5u3
10u3 + (-5u3)
10u3 + 5u3
5u3 + (-10u3)

-10u^3

5u^3

15u^3

-5u^3

Step-by-step explanation:

Given tiles

-15u^3+5u^3

10u^3+(-5u^3)

10u^3+5u^3

5u^3+(-10u^3)

Monomial : that type of polynomial in which only one term .

coefficient of like terms means  same viable with same power  -15 and 5 .

Therefore, coefficient of these two terms added and no change in power of u^3
