Question

help please

Answer 1

i understand that be=ed but what to do after that gets me.

Answer 2

BE=ED
find x and plug it in the value of ED

Answer 3

5x-10=3x+20
solve

Answer 4

how would i do that

Answer 5

i think 5 is the answer.

Answer 6

move 3x to the left side
5x-3x-10=20
2x-10=20
add 10 to both sides
2x=30
divide both sides by 2
x=15

Answer 7

Assuming that the given figure is told to be a parallelogram, you can proceed as Abdul told, it would be then true becaues the diagonals of a parallelogram bisect each other. Then you solve just as Abdul does and find out the value of x to find out the length of ED.

Answer 8

plug in the value of x in 3x+20
3(15)+20=45+20=65
