The coordinates of two vertices of a rectangle are (3, 7) and (-4, 7). If the rectangle has a perimeter of 30 units, what are the possible coordinates of its other two vertices? Select all that apply.
(3, -1) and (-4, -1)
(3, -7) and (4, - 7)
(3, 15) and (-4, 15)
(3, 15) and (4, 15)

include a picture of the drawing in order for me to

step-by-step explanation:

answer: its the third option.

step-by-step explanation:

i just took the test.

step-by-step explanation:

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
