<span>Depending on the equation there can be three possible cases:
1- There can be 1 specific solution for the variable:
2x+4= 3
where x= -1/2
2- there can be an infinite amount of solutions:
2x+x-2=3x-3+1
where x=x
3- there can be no answer:
3+2x-x=5-3x+4x
where the solution doesn't exist</span>
A, because parallelogram is the same as a rectangle, just tilted a bit. therefore the method is just base X height.
Supplementary angle is 180 degrees
The answer is D. In an ordered pair, the x-value, which tells you to move left or right, comes first, followed by the y-value, which tells you to move up or down.
