Answer:
x =2
SK = 21
KY = 13
SY = 34
Step-by-step explanation:
we can see from the picture the following:
SK + KY = SY equation 1
SK=13x-5 equation 2
KY = 2x+9 equation 3
SY = 36-x equation 4
using equation 2, equation 3 and equation 4 in equation 1 we have:
13x - 5 + 2x + 9 = 36-x
15x +4 = 36 - x
15x +x = 36-4
16x = 32
x = 32/16
x= 2
using x as 2 we evaluate it in equation 2, equation 3 and equation 4:
SK=13(2)-5 = 21
KY= 2(2) +9 = 13
SY = 36-2 = 34
We want to factor the following expression: (x 3)^2 14(x 3) 49(x 3) 2 14(x 3) 49(, x, plus, 3, ), squared, plus, 14, (, x, plus,

![[x^2 + 10x] + [10x + 100] = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%5E2%20%2B%2010x%5D%20%2B%20%5B10x%20%2B%20100%5D%20%3D%20%28U%20%2B%20V%29%5E2)
Factorize each group
![x[x + 10] + 10[x + 10] = (U + V)^2](https://tex.z-dn.net/?f=x%5Bx%20%2B%2010%5D%20%2B%2010%5Bx%20%2B%2010%5D%20%3D%20%28U%20%2B%20V%29%5E2)
Factor out x + 10
![[x + 10][x + 10] = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%20%2B%2010%5D%5Bx%20%2B%2010%5D%20%3D%20%28U%20%2B%20V%29%5E2)
So, we have:

Answer: 8.4
Length of rope bought by Sean = 68 3/4 inches
= 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
= 275/(4 * 15)
= 275/60
= 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope
the procedure and the method of solving is absolutely clear to you. This is the
easiest way to get to the solution for such problems.</span>
