Find the value of the variable and yz if y is between x and z. xy= 11, yz=4c, xz=83

 The required value of the variable c is 18 and that of YZ is 72.

Step-by-step explanation:  Given that Y is in between X and Z, where

XY= 11, YZ=4c and XZ=83.

We are to find the value of the variable c and YZ.

Since the point Y is in between X and Z, so we must have

And,

Thus, the required value of the variable c is 18 and that of YZ is 72.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

step-by-step explanation:

infinity is the answer
