Answer:
The first choice is the one you want
Step-by-step explanation:
Use geometric means to solve for a first. The formula is
and 64 = 15a and a = 64/15
That one was quite easy. Finding b is a bit more difficult.
The formula for finding b is

Solving for b:

Filling in we have
and
and
so b = 136/15
The answer is D, on a Graph, no two points can meet when drawn Vertically
When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by

which gets you

. Then multiply the second fraction by

to get

. Now you can add them together to get

.
(b)


now you can pull out root 2 and get

which equals
