Answer:
The answer is : 23.25 in ²
Step-by-step explanation:
There are 3 triangles with the same lengths: height = 5in and base = 5 in
There is one triangle: height = 4.3 in base = 5 in
Formula
Area = height x base / 2
For the triangles
Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²
For the triangle
Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²
Total surface area = 12.5 + 10.75 = 23.25 in²

Answer:
5 hours
Step-by-step explanation:
First, you set the equations equal, so 20h=17h+15
Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15
Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.
