Find the perimeter of triangle cde. round to the nearest tenth.

(1 point)
90.0
18.0
14.3
10.5

18.0

Step-by-step explanation:

The distance formula to find the distance between two points P(a,b) and Q(c,d) is :_

From the graph, the coordinates of ΔCDE are C(-3,1) , D(1,4) and E(3,-2).

Then, length of CD :-

Length of DE :-

Length of EC :-

Now, the perimeter of triangle :_

Hence, the perimeter = 18.0 units

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2
