just put values of a,b,c in the given equations

Answer 2

GIVEN:

• a = -25
• b = 20
• c = -10

TO FIND:

• a + (b + c) = (a + b) + c
• a × (b + c) = a × b + a × c

SOLUTION:

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

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

⇒ -25 + 20 - 10 = -25 + 20 - 10

⇒ -35 + 20 = -35 + 20

⇒ -15 = -15

(ii) a × (b + c) = a × b + a × c

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

⇒ -25 × 10 = -500 + 250

⇒ -250 = -250
