<h3>
Answer: Choice D. 4^2+5^2 = x^2</h3>
See note at the bottom
========================================================
The entire building is 20 feet. Fifteen feet of that is from the ground to the first landing of the stairs or fire escape. So 20-15 = 5 feet represents the height of the second set of stairs (leading to the roof of the building)
The base of the triangle is 4 feet as shown in the diagram. The height is 5 feet as found in the prior paragraph. Use the pythagorean theorem to say
a^2 + b^2 = c^2
4^2 + 5^2 = x^2
Note: If you meant to write 4^2+5^2 = x^2 for choice D, then that would be the answer. Otherwise, there is a typo somewhere.

Answer:
- <u><em>The cost of one rose bush is $ 9 and the cost on one bunch pf ornamental grass is $ 8.</em></u>
Explanation:
Name the variables and build a system of two equations with two unknowns.
<u>1. Variable r</u>: cost of one rose bush
<u>2. Variable g</u>: cost of one bunch of ornamental grass.
<u>3. First equation</u>:
- Shreya spent $68 on 4 rose bushes and 4 bunches of ornamental grass.
4r + 4g = 68
<u>4. Second equation</u>:
- Beth spent $115 on 11 rose bushes and 2 bunches of ornaments grass.
<u>5. System of equations</u>:
- 11r + 2g = 115 equation 2
<u>6. Solve the system</u>
a) Divide the equation 1 by 2:
- 11r + 2g = 115 equation 2
b) Subtract equation 1a from equation 2:
c) Substitute the value of r into the equation 1a:
<u>7. Conclusion</u>:
The cost of one rose bush is $ 9 and the cost on one bunch pf ornamental grass is $ 8.
