Question

Using the distributive property simplify completely

e) -(x+2y-4z)= f) 0.5 (4x+3y-8z)=

Answer 1

`-(x+2y-4z)= -x-2y+4z\\\\0.5 (4x+3y-8z)= 2x+1.5y-4z\\\\\sf Using~ the~ formulas: -(a-b)=-a+b\\ and~ a (b+c)=ab+ac`

Answer 2

−(x+2y−4z)

=−x−2y+4z




0.5(4x+3y−8z)

=(0.5)(4x+3y+−8z)

=(0.5)(4x)+(0.5)(3y)+(0.5)(−8z)

=2x+1.5y−4z
