Question

Given ABCD, AC = 28, and AE = 3x - 7, find the value of x.

Answer 1

I don't know what ABCD is?

Answer 2

this is ABCD

Answer 3

assuming it is a parallelogram, those diagonals bisect each other. So then AE would be half of AC.
like AE+AE=AC

2AE=AC...

Answer 4

So does 14 sound right?

Answer 5

idk
did you do 2AE first?

Answer 6

what is 2(3x-7)?

Answer 7

-1

Answer 8

how did you get -1 from 2(3x-7)?

Answer 9

x is a variable is varies so 2(3x-7) will also vary

Answer 10

2(3x)=?
2(-7)=?

Answer 11

\[2(3x+7)=2(3x+-7)=2(3x)+2(-7)=\]

Answer 12

what is 2(3)?
