7. if a figure has 3 sides, then it is a triangle
8. if a figure is not a triangle, then it does not have 3 sides
9. if a figure does not have 3 sides, then it is not a triangle
Distributive property means that you have to multiply everything directly outside the parent hes to everything inside the parentheses. For this problem multiply 7 to the 9x and to the -9 like so:
7(9x) + 7(-9)
63x + (-63)
63x - 63

Answer:
x=-5 or -5
Step-by-step explanation:
x - 4 = 2x + 1
Subtract x from both sides canceling out the x on the left, getting...
-4 = x + 1
Then subtract the 1 from both sides canceling out the 1 on the right, getting...
-5 = x
Subtracting x from 2x gets you 1x which you just write as x because there is only one x. Doing the equation from the other side will still get you the same answer and I will show you.
x - 4 = 2x + 1
-x - 4 = 1
-x = 5
x = -5
