Figure abcd is a parallelogram.
what are the lengths of line segments ab and bc?
a
3y - 2
b
ab = 4; bc = 16
oab = 4; bc = 8
ab = 10; bc = 20
oab = 10; bc = 28
2x - 4
x + 12
y + 6

First you need know that AB = DC and AD = BC.

So,

3y - 2 = y + 6

2y = 8

y = 4

AB = 3(4) - 2 = 12 - 2 = 10

2x - 4 = x + 12

x = 12 + 4

x = 16

BC = 16 + 12 = 28

So your answer is:

AB = 10; BC = 28

i think it's b
