Question

verify distributive property of multiplication over subtraction for a=-12 , b=5 and c=8​

Answer 1

Step-by-step explanation:

8x5= 40

then 40x-12=-480

Answer 2

Answer:

Hey Buddy here's ur answer

GIVEN :

Three Numbers,

a=-12, b=5 and c=8

TO VERIFY :

Distributive property of multiplication over subtraction

i.e. a(b-c) = ab - ac using the given numbers.

SOLUTION :

Distributive property of multiplication over

subtraction is

a(b-c) = ab - ac

It is given that a=-12, b=5 and c=8

so ,

a(b-c) = -12(5-8)

a(b-c) = -12(-3)

a(b-c) = 36 _______ LHS

• Now ,

ab - ac = (-12)(5)-(-12)(8)

ab - ac = -60-(-96)

ab - ac = -60 + 96

ab - ac = 36 ________(RHS)

•Since , LHS = RHS

=> a(b-c) = ab - ac

Hence verified
