Answer:
y = 45 and y = -45
Step-by-step explanation:
|y|/-3 = -15
Multiply each side by -3
|y|/-3 * -3= -15*-3
|y| = 45
The absolute value has 2 solutions, one positive and one negative
y = 45 y = -45
Answer:
x=6
Step-by-step explanation:
Since it's a parallelogram both of these parallel sides are equal so you can set up an equation like this:
4x-8=2x+4
Now solve.
4x=2x+12
2x=12
x=6
Answer:
B. 27 < AB < 81
Step-by-step explanation:
The triangle inequality requires that the length of any given side of a triangle be greater than the difference and less than the sum of the other two sides.

54 -27 < AB < 54 +27
27 < AB < 81

<em>Additional comment</em>
Some versions of the triangle inequality allow the "or equal to" case.
27 ≤ AB ≤ 81
Apparently, the one used here does not.
If the sum of the two short sides is equal to the long side, the "triangle" looks like a line segment. Its altitude and area are zero.
I believe the answer is...
2: <u>Negative</u>
Hopefully, this helps you!!
