Addition Property of Equality

Part A:

x = 6

Step-by-step explanation:

5(x + 2) = 6x + 3x - 14

use the distributive property for the left side of the equation

(in case you don't know, * means multiply)

combine like terms on the right of the equation.

Move the +10 on the left to the right (change the + to a - )

Move the +9x on the right to the left (change the + to a - )

All the like terms are together so now you can combine them.

divide both sides by -4 so the x is by itself

x = 6

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.
