Answer:
The perimeter of the square would be 8x - 16.
Step-by-step explanation:
Since the sides of the square all the same, you can just multiply the length of one side by 4 to find the perimeter. The perimeter is the distance around an object.
4( 2x - 4 ) = 8x - 16
Answer:
Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x
Step-by-step explanation:
Let us go through each of the equations one by one.
Equation A: 
This simplifies to

which has infinitely many solutions.
Equation B: 
this simplifies to


which is exactly one solution.
Equation C: 
this simplifies to


There's no way this is going to be possible; this equation has no solutions.
Equation D: 
this gives


which is exactly one solution.
Thus we see that it is equation C that has no solutions.
Answer: Yes Rozonda's definition is valid
Step-by-step explanation:
Answer:
-3/2
Step-by-step explanation:
y=mx +b
where m is the slope and b is the y intercept
we just need to rewrite 3x+2y+18=0 to look like that
We need to get y by itself
3x+18= -2y
we need y to be positive and to have no number in front of it (no coeficcent)
y= -3/2x-9
the slope is therefore -3/2
