Question

Find the length of BD such that ABCD is a parallelogram.
A.
7
B.
8
C.
10
D.
14

Answer 1

DE = EB

you can solve for y from that

Answer 2

4y-5 = 2y+1 ?

Answer 3

yep

Answer 4

so y=3
put that into the length to figure BD

Answer 5

I'm confused :o

Answer 6

4y - 5 = 2y + 1

4y - 2y = 1 + 5

2y = 6

y = 3

Answer 7

ohh so 6=6 ?

Answer 8

yes, just divided both sides by 2 for the last step

Answer 9

6/2 = 3

Answer 10

right, y=3

Answer 11

Now that you know what y is, you can calculate the length of BD

BD = (4y - 5) + (2y + 1)
= (4*3 - 5) + (2*3 + 1)
= 7 + 7
= 14

Answer 12

ohh thank you, I was confused as to what equation I was suppose to plug 3 into haha!

Answer 13

no prob
