Question

.Figure ABCD is a rectangle. The length of segment AE is (5x - 7) units and the length of segment EC is (2x - 1) units.
What is the length of diagonal BD

Answer 1

no answeres i just want to know how to do it
8 units

6 units

12 units

10 units

Answer 2

since this is a rectangle, we know the diagnols bisect each other. i.e.,

5x-7 = 2x -1

solve for x here and to get the length of the diagnol, plug x into 2(2x-1). and that will be your answer.

Answer 3

kk thanks i will work it out but i might post it so that i can know if i am right or not

Answer 4

k.. did you get x= ?

Answer 5

not yet hold on

Answer 6

yep..

Answer 7

i got 10 units for the answer

Answer 8

hmmm. what did u get for x?

Answer 9

Answer 10

i got x=2...

Answer 11

5x-7 = 2x -1

subtract 2x from both sides
5x - 2x - 7 = 2x - 2x - 1
3x - 7 = -1

add 7 to both sides
3x - 7 + 7 = -1 + 7
3x = 6
x = 2

Answer 12

o okay i see what i did wrong thatnks alot

Answer 13

yw.. :)
thanks for working the problem with me...:)

Answer 14

np:D

Answer 15

:)
just to be clear, length of the diagnol is 6 right?

Answer 16

yeppers thanks for showing me how to do it do :D
