Rectangle A and B.
rectangle B is 8x12 and if you divide 8 and 12 by 4 you get 2x3
1.vertex form is 
to get into vertex form, complete the square
step 1: group x terms
step 2: factor coefient in front of x^2 term
prep for next step: take 1/2 of linear (1st dgree term) and square it
, 
step 3: add positive and negative of that previous number inside the parenthasees
factor perfect squaer trionmial
take out that -36 by expansion
2. factor out the 2
what 2 numbers multiply to get 12 and add to get 8?
2 and 6
3.
for 
in our case
a=1, b=-7, c=-6
so 
and 
4. remember that 
so 
treat 
as a variable

Answers:
<h2>17. B</h2><h2>18. B</h2>
Step-by-step explanation:
17. We need to understand what an indirect proof is. In an indirect proof, you prove a statement by showing that the negation of the statement is false.
The "then" part of the conditional is the "to prove" statement.
In an indirect proof, we assume the opposite of what we want to prove, this is also called proof by contradiction.
So if we need to prove angle A is not an obtuse angle, we will assume it is and then use the proof format to show that angle A cannot be obtuse.
<h2>The answer is B: Assume angle A is an obtuse angle</h2>
18. This question is asking us to use an indirect proof again. The "then" part of the statement is "KL > JK" and is the "to prove" statement.
We need the opposite of this, which would be assuming that KL <u><</u> JK.
<h2>The answer is B: Assume that KL <u><</u> JK</h2><h2>I'm always happy to help :)</h2>
