You can solve this problem by doing distributive property. 

So, 2(x + 7) + 10 \\ \\ 2(x) = 2x \\ \\ 2(7) = 14 \\ \\ \\ (2x + 14) + 10  \\ \\ \\ 14 + 10 = 24 \\ \\ \\ \\ Answer: 2x + 24

Help pleasee asap! im super confused
dem82 [27]

Answer:

  x = 4

Step-by-step explanation:

A midpoint divides the segment into two equal parts. Each is half the length of the whole.

  XY = (1/2)XZ

  5x+4 = (1/2)(8x +16)

  5x +4 = 4x +8

  x = 4 . . . . . . . . . subtract 4x+4 from both sides

_____

<em>Check</em>

5x+4 = 5(4)+4 = 24

8x+16 = 8(4) +16 = 48

So, XY is half of XZ.
