Answer:
Where's the question?
Step-by-step explanation:
{ x + 3 y = 7 * ( - 2)
2 x + 4 y = 8
{ - 2 x - 6 y = - 14
2 x + 4 y = 8
_______________
-2 y = - 6 * ( -1)
2 y = 6
y = 6 / 2
y = 3
For x :
2 x + 4 y = 8
2 x + 4 * ( 3) = 8
2 x + 12 = 8
2 x = 8 - 12
2 x = - 4
x = - 4 / 2
x = - 2
Solution: x = -2 and y = 3
hope this helps!
First of all, we know that the two angles are 90 degrees each. That means that the other two angles are also 90 degrees each
(rectangle = 360 degrees total)
This means that the two sides (Side FG and Side EH) are congruent.
That means that the sides EF and GH are also congruent.
This shape is a rectangle
Hope this is gonna help at least a bit ;)
