Choice D

1/2 to the left 4 1/2 down

m + 2 = 17

subtract 2 from both sides

m + 2 - 2 =17 - 2

simplifying

m = 15

answer

15

**Answer:**

Since the points X , Y and Z are collinear:

For the diagram, you just have to draw a line and mark the end-points of the line as X and Z and mark the mid-point of the line as Y

Since we are given that XY = YZ,

We will replace with the provided values:

XY = YZ

<em>4(x + 5) = 2(x + 11)</em>

<em>4x + 20 = 2x + 22</em>

<em>2x = 2</em>

**x = 1**

**Since x = 1 and XY = YZ,**

**We can say that: **

XZ = XY + YZ

**XZ = XY + XY or XZ = 2XY**

Now, replacing the variables for the value of XZ

XZ = 2XY

XZ = 2(4x + 20)

XZ = 2(4 + 20) (Since x = 1)

**XZ = 48 units**
