Justify each step of the solution by stating the property that was used to get to each step. given: 4(-6x – 3) + 24x = -72x + 132 -24x – 12 + 24x = -72x + 132 step 2: –12 = -72x + 132 step 3: -144 = -72x step 4: 2 = x

First is the distributive property. then you add 24x to each side, giving you -12=96x+132.  You then subtract 132 from each side giving you -144=96x. To get the variable "x" by its self, you divide each side by 96 giving you x=-1.5

answer: i think it's a

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
