PLEASE HELP choose ALL that define a rectangle in the coordinate plane by the four given points

1. A(-4,0), B(3,2), C(4,-2), D(-2,-3)
2. A(0,0), B (2,2), C(7,-3). D(5,-5)
3. A(-2,6). B(4,3), C(2,-1), D(-4,2)
4. (-3,-4), B(-1,2), C(2,1), D(0,-5)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

answer: #1 ads up by 8 and i don't know #2
