Question

Use the distributive property to expand the expression. −13x − (3y − z) + 5

Answer 1

-13x-3y+z+5.( expand it by multiplying contents of brackets on a negative sign.).

Answer 2

The distributive property lets us multiply a sum by multiplying each addend separately and then add the products.a(b+c)=ab+ac .a is distributed to both b and c to give ab+ac.

The given expression is −13x − (3y − z) + 5

There is no number before the parenthesis so we can write 1 there

−13x −1 (3y − z) + 5 There is a - sign before the parenthesis so the sign will change when we use the distributive rule.

−13x −1 (3y − z) + 5 =-13x-3y+z+5.
