Answer:
Please, refer to the images below
Step-by-step explanation:
We need to solve for x in the equation
cos (x+ pi) ^2 = sin (x)
cos (x+ pi) = - cos(x)
(-cos (x)) * (-cos (x)) = sin(x)
cos(x) ^2 = sin(x)
We know that
cos(x) ^2 + sin(x) ^2 = 1
cos(x) ^2 = 1 - sin(x) ^2
1 - sin(x) ^2 = sin(x)
sin(x) ^2 + sin (x) -1 = 0
Let A = sin(x)
A^2 + A - 1 = 0
(solutions attached in picture 1)
This means that
x = arcsin(A)
(solutions attached in picture 2)

Hope it helps!
I'm guessing we are solving for a unknown variable? This question is hard to understand, if you are not solving for a unknown variable than tell me in the comments and ill fix my answer
(X*4-14)*6=18
If I am correct your answer is 4.25
(4.25x4-14)*6=18
If I did the problem wrong than tell me. To me this question makes no sense so i'm not sure if I did it wrong.

Answer:
opposite sides have the same slope, so it is a parallelogram
Step-by-step explanation:
A parallelogram has opposite sides that are parallel. Here, one pair of opposite sides consists of horizontal lines. Both have zero slope, so are parallel.
The other pair of lines each has a "rise" of 3 units for each "run" of 2 units, so the lines have a slope of 3/2. Both lines have the same slope, so are parallel.
Since opposite sides are parallel, the figure is a parallelogram.
