Answer:
x = 16
Step-by-step explanation:
Step 1: We know DF - DE = EF
9x - 39 - 47 = EF
Step 2: Simplify
9x - 86 = EF
Step 3: Set the equation equal to 3x + 10
9x - 86 = 3x + 10
6x = 96
x = 16
Therefore x is equal to 16

The math books can all be in the middle with the other two on the sides, or the math books can be on the left side with the other books at the right side. Also, the math books can be on the right side with the other books at the left side.
Answer:
![m=(y-b)/x](https://tex.z-dn.net/?f=m%3D%28y-b%29%2Fx)
Step-by-step explanation:
we have
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Solve for m
That means -----> isolate the variable m
Subtract b both sides
![y-b=mx+b-b](https://tex.z-dn.net/?f=y-b%3Dmx%2Bb-b)
![y-b=mx](https://tex.z-dn.net/?f=y-b%3Dmx)
Divide by x both sides
![(y-b)/x=mx/x](https://tex.z-dn.net/?f=%28y-b%29%2Fx%3Dmx%2Fx)
![(y-b)/x=m](https://tex.z-dn.net/?f=%28y-b%29%2Fx%3Dm)
Rewrite
![m=(y-b)/x](https://tex.z-dn.net/?f=m%3D%28y-b%29%2Fx)

Add 114,92 and 62 together you'll get 268. A polygon with 4 sides the angles have to equal to 360. So subtract 360 from 268. Then you'll get your answer of 92
