==========================================
Work Shown:

This shows why choice B is the answer.

Explanation:
- In the second step, I multiplied top and bottom by

- This is so we can apply the difference of squares rule in step 3. The difference of squares rule is (x-y)(x+y) = x^2-y^2.
- In step 4, the square roots cancel out with the squaring operation. The two operations are inverses of one another, which is why they cancel.
So in general, if the denominator is
and you want to rationalize the denominator, then you should multiply top and bottom by
. The same applies in reverse as well.
This leads to the denominator becoming 
Keep in mind that
and

Answer: The answers are in the steps.
Step-by-step explanation:
A) 4
= 9/2 * 13 = 117/2
B ) 13 ( 58 + 1/2)
= 754 + 6.5
= 760.5
Answer:
b
Step-by-step explanation:
Given K is the midpoint of JL, then
JK = KL ← substitute values
6x = 3x + 3 ( subtract 3x from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Hence
JK = 6x = 6 × 1 = 6
KL = 3x + 3 = (3 × 1) + 3 = 3 + 3 = 6
JL = 6 + 6 = 12
