GEOMETRY HIGH SCHOOL
In rectangle ABCD, diagonals and AC BD intersect at E. If AC= 4x + 8 and BE = x + 2, then the length of diagonal AC is ____ ?

Answer 1

Answer:

AC = 8

Step-by-step explanation:

AC = 4x + 8

BE = x + 2

x + 2 = x + 2

2x = 2 - 2

2x = 0

2x\2 = 0/2

x = 0

AC = 4x + 8

AC = 4(0) + 8

AC = 0 + 8

AC = 8

Answer 2

When the AC= 4x + 8 and BE = x + 2, so the length of diagonal AC is to be considered as the 8.

Calculation of the length of diagonal AC:

Since

AC = 4x + 8

BE = x + 2

Now

x + 2 = x + 2

2x = 2 - 2

2x = 0

x = 0

Now

AC = 4x + 8

AC = 4(0) + 8

AC = 0 + 8

AC = 8

hence, the length of diagonal AC is to be considered as the 8.
