4(2n - 9) = 10n - 8
8n - 36 = 10n - 8
8n - 8n - 36 = 10n - 8n - 8
-36 = 2n - 8
-36 + 8 = 2n - 8 + 8
-28 = 2n
-28/2 = 2n/2
-14 = n
Answer:
104 units
Step-by-step explanation:
Given
Shape: Rhombus


Required
Determine the perimeter
The given parameter are the diagonals of the rhombus.
The perimeter (from diagonals) is calculated as thus:

Substitute values for JL and KM





<em>Hence, the perimeter is 104 units</em>
A= 15+z+ square root 17(z+15)/ z-2
z=2a^2/(a-1)^2 + 30a/(a-1)^2 - 15/(a-1)^2
