Question

Use the distributive property to expand the following expression. -2(2.1x + 3y - 1.8)

Answer 1

-2 ( 2.1 x +3 y - 1.8 = - 4.2 x -6 y + 3.6

Explanation:

Answer 2

-2 ( 2.1 x +3 y - 1.8 = - 4.2 x -6 y + 3.6

Explanation:

Distributive property:-

distributive law

let a , b, c are two real numbers and by using distributive law is

a.(b+c) = a.b + a.c

given -2 ( 2.1 x +3 y - 1.8) = -2 . (2.1)x + (-2).3 y + (-2).(-1.8)

now simplification right hand side

-2 ( 2.1 x +3 y - 1.8 = - 4.2 x -6 y + 3.6
