Givens

Andrea: K

Me: 5k - 4

Sum

k + 5k - 4 = 14

Solve

6k - 4 = 14              Add 4 to both side.

6k - 4 + 4 = 14 + 4

6K = 18                  Divide by 6

k = 18/6

k = 3

If DE=4x+10, EF =2x-1, and DF=9x-15, find DF
svetoff [14.1K]

Answer:


Step-by-step explanation:

If DE = 4x+10,EF =2X -1, and DF= 9x - 15 find DF

(de + ef ) - df = 2e || 2e/2 = e || ed - e = d || ef - e = f || f + d =  df

de + ef = 6x + 11 || (6x +11) - df = -3x -6 || 2e/2 = -3x/2 - 3  || (-3x/2 - 3) - de = x/2 + 7||  (- 3x/2 - 3) - ef = -x/2 - 1|| d + f = 6
