Answer:
see explanation
Step-by-step explanation:
from the diagram
DF = DE + EF , that is
4x + 2 = x + 7 + 7
4x + 2 = x + 14 ( subtract x from both sides )
3x + 2 = 14 ( subtract 2 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Then
DE = x + 7 = 4 + 7 = 11
DF = 4x + 2 = 4(4) + 2 = 16 + 2 = 18
Should be D.
Both have a magnitude of 5

Answer:
if you were solving for X the answer would be x < 3
Step-by-step explanation:
Hostas would be $2 each and Shrubs would be $6 each
Use distance formula to get a distance function in terms of x representing the distance from a point on curve (x,y) to point (3,0)
y = 8/x
Minimize the function by setting derivative equal to 0.
Simplify and solve for x
This becomes a 4th degree polynomial, you can use graphing calculator to find zeros.
Also intuitively you can recognize that 64 = 4^3, so if x=4 you get
1 = 1
Therefore x=4 is a solution, substituting give y =2
