Answer 1

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  $-5u^3$.

Answer 2

Answer:

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

$5u^3-10u^3 =-5u^3$
