Answer:
1 solution.
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
9(z + 8) = -9z - 72
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 9: 9x + 72 = -9z - 72
- Add 9z to both sides: 18z + 72 = -72
- Subtract 72 on both sides: 18z = -144
- Divide 18 on both sides: z = -8
Here we see that we will get only 1 solution for <em>z</em>.

Answer:
The formula for the area of a parallelogram is bh.
15(h) = 300
h = 20
The height of the parallelogram is 20 yards.
Answer:
The formula to find the area of a rectangle is:
b * h = a
where b = base, h = height, and a = area.
The formula to find the area of a triangle is:
(1/2) * b * h = a
where b = base, h = height, and a = area.
They are similar because in both of the formulas, you are multiplying the base by the height. The difference is that in the triangle formula, you have to do an additional step of multiplying by (1/2) to get the area. hope this helps:)
