Answer:
7x-6
Step-by-step explanation:
x+3+3x-18+3x+9 (Add like terms)
(x+3x+3x) (3-18+9) (solve) ( x is the same as 1x)
(7x) (-6)
7x-6
If we have 2 dices rolling, we have all 6x6=36 different ways.
But for the sum of the two being 4, we have (1;3), (3;1) and (2;2), only 3 ways.
And we calculate the probability : 3:36= 1/12
Have fun
X=-25 is the answer for the problem listed above.
Since we know that a square has all equal sides, we can simply divide the perimeter by 4 to get each side length.

Using the information above, we can see that each side is
3x+13 units.
Hi there!

To find the graph we need to plug in different values of X into the equation. When we plug in these x-coordinates we can find the y-coordinates of our points.
