14. For what values of x and y is quadrilateral ABCD a parallelogram? 8x-10
B
5y-12
4x-1
D
4x+14
C
a. r= 1, y = 3
b. x=6, y = 7
c. x=11, y = 7
d. x=6, y = 11

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

the answer for the second equation is (4,0)

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
