Answer:
Choice B is correct
Step-by-step explanation:
The given radical division can be expressed in the following form;

Using the properties of radical division, the expression can be expressed in the following form;

Simplifying further yields;

Choice B is thus the correct alternative
Step-by-step explanation:
You're given that ΔUVW is similar to ΔYZW. The tricky part is identifying which sides in ΔUVW correspond to which sides in ΔYZW.
The triangles share point W, so visually rotate one triangle around W until the two triangles align. That way, you can see that UW and ZW correspond to each other, and VW and YW correspond to each other.
Now you can find the scale:
VW / YW = 5/12
And you can write a proportion to find x:
UW / ZW = VW / YW
x / 64 = 5 / 12
x = 26 ⅔
X = 12400
20/100 = 1/5
2480 x 5 = 12400
You just add the number together
