-14h^3-6h^2 here is the answer
Answer:
WT = 34
Step-by-step explanation:
The ultimate goal here to pinpoint what x is equivalent to. In a rectangle we know that the diagonals are congruent as well as the fact that they bisect each other. This means cutting in half. Using this knowledge we know VW = 9x - 11 is half of SU = 16x - 12.
Step One: Multiply 9x - 11 by 2.
2(9x - 11) = 18x - 22
Step Two: Set up your equation
18x - 22 = 16x - 12
Step Three: Solve for x
18x - 22 = 16x - 12
2x - 22 = -12
2x = 10
x = 5
Step Four: Substitute to check your work
16(5) - 12 = 68
9(5) - 11 = 34
Again, since the diagonals of a rectangle bisect each other VW = WT.
34 is half of 68 proving our findings.

Answer:
Step-by-step explanation:
Let x = degrees of the largest angle.
The smallest angle is two thirds the size of the largest, so the smallest angle is (2/3)x.
The middle angle is 4 degrees less than the largest, so it is x - 4.
The largest angle is of course x.
So add all three angles to equal the total degrees, which you have not provided. If you do have it and just forgot to post it, here is the formula:
(2/3)x + (x - 4) + x = ?
(8/3)x - 4 = ?
(8/3)x = ? + 4
x = (3/8)? + 1.5
