Answer 2

Solution:

It is given that:

• a = -25
• b = 20
• c = -10

In the first part of the question, we are asked to verify the associative property of addition.

a + (b + c) = (a + b) + c

⇒ -25 + (20 - 10) = (-25 + 20) - 10

⇒ -25 + 10 = -5 - 10

⇒ -15 = -15

For second part:

This is about distributive property of multiplication over addition.

a × (b + c) = (a × b) + (a × c)

⇒ -25 × (20 - 10) = (-25 × 20) + (-25 × -10)

⇒ -25 × 10 = -500 + 250

⇒ -250 = -250
