N^2 + 2n + 1 = 2n + 50 - Square both sides
n^2 + 2n + 1 - 2n - 50 = 0
n^2 - 49 = 0 - simplify
(n + 7)(n - 7) = 0 factor
n + 7 = 0. n - 7 = 0
n = -7, n = 7

If CF = 5, CD = 12, and EF = 5, what is the perimeter of triangle CDE?

Basile [38]

Answer:

The perimeter of triangle CDE is 34.

Step-by-step explanation:

To find the perimeter of a triangle, you have to add all the sides together, since this looks like a isosceles triangle, you would make side ED also 12 and then just add them all together.

12+12+5+5= 34.
