Answer:
Question A)

Question B)

Question C)

Step-by-step explanation:
A)
We are given:

We can rewrite the expression:

The square root and square will cancel each other out. Thus:

B)
We are given:

Rewrite:

Note that the square root of 9 is simply 3. We can also factor the second part:

Rewriting:

Simplify:

C)
We are given:

Rewrite. Note that 50 = 25(2):

Simplify. We can rewrite the factor as:

The square and square root will cancel out. Thus:

Answer:
an isosceles right triangle
Step-by-step explanation:
The square of the length of a side can be found from the distance formula:
d^2 = (x2-x1)^2 +(y2-y1)^2
The square of the length of WX is ...
WX^2 = (-3-(-10))^2 +(-1-4)^2 = 49+25 = 74
The square of the length of XY is ...
XY^2 = (-5-(-3))^2 +(11-(-1))^2 = 4 +144 = 148
The square of the length of YW is ...
YW^2 = (-10-(-5))^2 +(4 -11)^2 = 25 +49 = 74
The sum of the squares of the short sides is equal to the square of the long side, so this is a right triangle. The squares of the short sides are equal, so this is an isosceles right triangle.
