Answer:
C) 1
Step-by-step explanation:
3/(x-3)=x/(x-3)-3/2
6/2(x-3)=2x/2(x-3)-3(x-3)/2(x-3)
6=2x-3(x-3)
6=2x-3x+9
x=3
x=3 makes the denominator x-3 a zero, so the solution is extraneous,
The total area of the regular pentagon prism is 485 square units
<h3>How to determine the surface area?</h3>
The given parameters are:
Base area = 50
Height = 11
Base = 7
Start by calculating the total area of the 5 sides using
Sides = n * Height * Base
Sides = 5 * 11 * 7
Sides = 385
The total surface area is
Total = 2 * Base area + Sides
This gives
Total = 2 * 50 + 385
Evaluate
Total = 485
Hence, the total area of the regular pentagon prism is 485 square units
