Answer:
5/6 of the time or 50 minutes
Step-by-step explanation:
I think it’s called tromino
The first thing we must do for this case is to find the relationship between the variables.
We have then:

From here, we clear the value of "Y":


On the other hand we have:

From here, we clear the value of "x":

Then, replacing values we have:

On the other hand:

Finally, the perimeter is given by:

Substituting values we have:

Answer:
the perimeter of ABCD is:
44 units
Answer:
Functions: y = -x + 11, y = 2x^2 - 6x + 4, y = 7
Not Functions: x = 3, x^2 + y^2 = 81, y^2 = -5x - 12
