Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:
√72 - √8 + √128 separate the terms into square roots
√36·2 - √4·2 + √64·2 square root the terms that you can
6√2 - 2√2 + 8√2 they have like radical terms, so combine the terms
6 - 2 + 8 = 12 the coefficients are 12 when combined
12√2 this is the EXACT VALUE of the expression

The measure of XW from the given diagram is 9. Since ZY = XW, hence ZY is also 9
Find the diagram of the question attached
From the diagram, ZY = XW
- ZY + YX = ZX
- YX + XW = YW
Subtract both expressions;
ZY - XW = ZX - YW
Since ZY = XW
The equation becomes XW - XW = ZX - YW
ZX - YW = 0
Given the following parameters
ZX = 5x + 17
YW = 10 - 2x
5x + 17 = 10 - 2x
5x + 2x = 10 - 17
7x = -7
x = -1
Get the measure of ZY and XW
XW = YW - YX
XW = 10 - 2x - 3
XW = -2x + 7
XW = -2(-1) + 7
XW = 2 + 7
XW = 9
Hence the measure of XW from the given diagram is 9. Since ZY = XW, hence ZY is also 9
