Question

If a = -35, b = 10 cm and c = -5, verify that:
(i) a + (b + c) = (a + b) + c
(ii) a × (b + c) = a × b + a × c
pls give step by step explanation also

Answer 1

Answer:

i) -30

ii) -175

Step-by-step explanation:

given that a=-35, b=10 and c=-5

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

(-35)+{10+(-5) } = {(-35)+10}+(-5)

-35+5 = (-25)+(-5)

-30 = -30

ii)a×(b+c) = a×b+a×c

-35×{10+(-5)} = (-35)×10+(-35) × (-5)

-35×5 = -350+175

-175 = -175
