A is 400
E I don't know soory
Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10

Hope that helped. Good luck.
The answers I have gotten are
A- x+y= $25
B- $95
1. distance = √((x₂-x₁)²+(y₂-y₁)²)= radius of the circle.
distance = √((4-(-3))²+(5-(-2))7²) = √98
2. (x-k)²+(y-h)²=r² center (-3,-2) which is (k,h)
(x-(-3))²+(y-(-2))²= (√98)²
(x+3)+(y+2)² = 98 is the equation
The answer is
<em>False

<em />A Perfect Square Trinomial should be in the form of this:
The following,
, definitely does not follow the rule given and, therefore, is not a Perfect Square Trinomial.
I hope this helped!! Have an amazing day :)
