Question

Can someone tell me what I'm doing wrong. See attached

Answer 1

one property of a rectangle is that the diags are equal right?

Answer 2

yeah congruent

Answer 3

another property is that the parts the stem out of the middle point (E) are all equal as well

AE = EC, can you set up that equation?

Answer 4

2x+1=x+7
Right?

Answer 5

yes, now lets see how youre solving that for x please

Answer 6

2x+1=x+7
-2x -2x
x+1=7
x=6

Answer 7

good,

now, would you agree that half of a diagonal is equal to .. pick on of the equations ... say

x+7 ?

Answer 8

yeah

Answer 9

so, if half a diag is equal to 6+7, then we would have to double that to get the full length ....

2(6+7) = diag langth

Answer 10

which equals 26

Answer 11

i like 26 :)

Answer 12

oh, thanks! :)

Answer 13

youre welcome, and good luck

Answer 14

I assume this is a typo?
2x+1=x+7
-2x -2x <----- this should be -x not -2x
x+1=7
x=6

but you do get the correct answer (how?)
