Answer: 
a = 2 and b = 3
==================================================
Explanation:
Let's expand out
to get the following:

The x term here is 2ax
Compare this to the x term of
and we see that

--------------
The constant term of
is the
portion since it doesn't have the variable x attached to it.
Compare this with the 7 of
which is also the constant.
Equate the two items, plug in a = 2 and solve for b.

Therefore,

Answer:
No
Step-by-step explanation:
7 9/16 - 2 3/4 = 4 13/16
Hey!
The formula for finding the length of the hypotenuse is:

That means you have to square both numbers.

That gives you:

<em>That means your answer is the first choice</em>

The slope is the change in y over the change in x
so
0 - - 2/ -2 -0
2 / -2
or simplified to -1
Hope this helps :)
