Step-by-step explanation:
Simplify the radical:
1.We must write the radicand as a product, and then we must use the product property for simplicity.
The roof of is equal =
2.We must use the property of the product:
=
C
<em>u = 21</em>
WX = XY because (VW = VY)
WX = u + 42
XY = 3u
u + 42 = 3u
42 = 3u - u
42 = 2u
u = 42 / 2
u = 21
