The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
I hope this helps you
x^2-15x+36
x -3
x -12
(x-12)(x-3)
22 increases by 0.9
24 increases by 4 and 1/2
25 increases by 4.3
Just subtract the number from the number after it to find how to find the next numbers in the sequence

[(455 + 180 + 324 + 675)/(65 + 36 + 54 + 75)] = 7.10
Answer is D.
Add the ratio numbers to be your denominator
5+3+7+1=16
Pieces:
5/16 x124=38.75
3/16 x124=23.25
7/16 x124=54.25
1/16 x124=7.75
