Hello from MrBillDoesMath!
Answer:
x = 12
Discussion:
From the diagram, the two triangles appear to be similiar. Then
28/7 = (6x + 28) /25
as the ratio of corresponding parts of similar triangle are the same.
28/7 = (6x +28)/25 => simplify. 28/7 = 4
4 = (6x + 28)/25 => multiply both sides by 25
4*25 = 6x + 28 => simplify, 4 * 25 = 100
100 = 6x + 28 => subtract 28 from both sides
100 -28 = 6x => simplify. 100 - 28 - 72
72 = 6x => divide both sides by 6
72/6 = 12 = x
Thank you,

Answer:
36.8/2.8 = 16
Expression 1 = 368/28
Expression 2 = 3.68/.28
Step-by-step explanation:
If you move the decimal the same on both numbers of a division problem the answer stays the same.
Answer:
A=384 
Step-by-step explanation:
A =2(wl+hl+hw)
A=2(8*8+8*8+8*8)
A=2(64+64+64)
A=2(192)
A=384
Remark
You have to stare at this for a moment before you catch on. When you fold the arc into a circle, 8pi becomes the circumference of the base circle.
Formula
C = 2*pi*r
C = 8pi
Solution
8pi = 2pi * r Divide both sides by 2pi
8pi / 2 pi = r
4 = r Answer
