Answer:
x=19
Step-by-step explanation:
The perimeter of the right triangle is
P=9+12+15 =36
The perimeter of the left triangle is
P =x-7+ x-7+ x-7 = 3x-21
Set them equal
36 = 3x-21
Add 21 to each side
36+21 = 3x-21+21
57 = 3x
Divide each side by 3
57/3 = 3x/3
19 =x

Answer:
Addition property of equality
Step-by-step explanation:
3/4 was added to each side
Answer =-3 or -3/1
You can either do rise/run
Or you can find two points on the line and do (y2-y1)/(x2-x1)
Two points on the line are (-1,2) and (-3,-4)
X1=-1 Y1=2
X2=-3 Y2=-4
(y2-y1)/(x2-x1) = (-4-2)/(-3-(-1)) =(-6)/(-3+1)
=-6/-2 = -3
So slope =-3/1 or -3 (same thing)
