Question

verify ax(b+c) =axb + axc
​

Answer 1

Step-by-step explanation:

First evaluate the expression a(b+c)

From the given values, it follows that

a(b+c)=—10(-9+8)=—10(—1)=10

Now evaluate the other expression which is

ab+ac

=—10(-9)+(—10)(8)

=90–80=10=a(b+c)

Thus

a(b+c)=ab+ac for given values of a,b and c.

Remark: You may also evaluate the second expression or the right hand side of the equation before the left hand side. In either way, you will get the same answer i

Answer 2

This question van be solved showing distributive property of multiplication over addition

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

-2(9+(-2))=(-2*9)+(-2*-2)

-2*7=-18+4

14= -14
