Answer 1

To find : Add each pair of monomials and match it to correct.

Solution :

To match we solve the monomials.

1.
`-15u^3 + 5u^3`

Adding

`-15u^3 + 5u^3=-10u^3`

2.
`10u^3 +(-5u^3)`

Adding

`10u^3-5u^3=5u^3`

3.
`10u^3 + 5u^3`

Adding

`10u^3 + 5u^3=15u^3`

4.
`5u^3+ (-10u^3)`

Adding

`5u^3-10u^3 =-5u^3`

Answer 2

Consider the given monomials. Let us determine the sum of these monomials,

1.
`-15u^3+5u^3`

=
`-10u^3`

Therefore, the sum of the given monomials is
`-10u^3`.

2.
`10u^3+(-5u^3)`

=
`10u^3-5u^3`

=
`5u^3`

Therefore, the sum of the given monomials is
`5u^3`.

3.
`10u^3+5u^3`

=
`15u^3`

Therefore, the sum of the given monomials is
`15u^3`.

4.
`5u^3+(-10u^3)`

=
`5u^3-10u^3`

=
`-5u^3`

Therefore, the sum of the given monomials is
`-5u^3`.
