Answer:
4 pieces of chair rail are needed
Step-by-step explanation:
<u>Step 1: Calculate the perimeter of the room</u>
Perimeter of rectangle = 2L + 2B
Length = 18
Breadth = 14
Perimeter of room = 2(18) + 2(14)
Perimeter of room = 64 feet
<u>Step 2: Calculate the pieces of chair rail needed</u>
<em>Perimeter of room = 64 feet</em>
<em>Length of each chair rail = 16 feet</em>
<em>Total chair rails needed = Perimeter of room/length of each chair rail</em>
<em>Total chair rails needed = 64/16</em>
Total chair rails needed = 4
Therefore, Mr. Herzog needs 4 pieces of chair rails.
Hey there!
60 - 34 = 26
x = 26
Hope this helps
Have. great day (:
8p² - 16p = 10
8p² - 16p - 10 = 0 Divide through by 2
4p² - 8p - 5 = 0
Multiply first and last coefficients: 4*-5 = -20
We look for two numbers that multiply to give -20, and add to give -8
Those two numbers are 2 and -10.
Check: 2*-10 = -20 2 + -10 = -8
We replace the middle term of -8p in the quadratic expression with 2p -10p
4p² - 8p - 5 = 0
4p² + 2p - 10p - 5 = 0
2p(2p + 1) - 5(2p + 1) = 0
(2p + 1)(2p - 5) = 0
2p + 1 = 0 or 2p + 5 = 0
2p = 0 -1 2p = 0 - 5
2p = -1 2p = -5
p = -1/2 p = -5/2
The solutions are p = -1/2 or -5/2
