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

answer:

-4.1x - 6y + 3.6

step-by-step explanation:

to distribute all you have to do is multiply -2 by everything

-2(2.1x) + (-2)(3y) - (-2)(1.8)

-4.1x - 6y + 3.6

answer: (-4.2x-6+3.8)

step-by-step explanation:

-2 times 2.1x = -4.2x,

-2 times 3y = -6y,

-2 times -1.8 = 3.8

put them together in the equation and that's what you get.
