I am not very sure ask someone se
Answer:
B
Step-by-step explanation:
-2 x -0.7 + 3.2 = 3.2
15/2 r -40, the first answer
I think the question for this problem is to find the slope of the staircase. The slope is a ratio of change of the y-coordinates and x-coordinates of points. It is written as Δy/Δx especially in analytical geometry. It could also be simply the ratio of the rise or vertical height to the run or horizontal length.
Therefore, the slope of the stair case is
Slope = rise/run = 14/20 = 0.7
This is like property of a parallelogram you have to do is basically follow its properties which is opposite sides are congruent
so we solve like this

subtract -3 on each side one is canceled since its equal to zero
and other is -3-5= -8

now subtract -3 on each side
-3x-x is -4 so,
-4x=8
divide its equal to 2
X=2
Hope it helps! have an awesome day you should probably study the properties of parallelogram
