Answer:
Hey there!
Let's solve our equation below.
-2(x+3)= -2(x+1)-4
Let's distribute the parentheses.
-2x-6=-2x-2-4
We combine like terms.
-2x-6=-2x-6
We add 6 to both sides.
-2x=-2x
We divide both sides by -2
x=x
If, when solving an equation, you get one number or variable that equals itself, there are infinitely many solutions.
We can plug anything into this equation and it will always equal to same things, since x is just equal to whatever x value you want.
Therefore, there are infinitely many solutions.
I hope this helps!

Step-by-step explanation:
Answer:
The distance between these two is 3 3/5
Step-by-step explanation:
In order to find the distance between two points, we subtract one from the other. Then if the result is negative, we take the absolute value.
2 3/5 - -1
2 3/5 + 1
3 3/5
Answer:
x=7
y=18
The length of each of the two shorter sides is 14.
The length of each of the two longer sides is 19.
Step-by-step explanation:
2x+5 = x+12 and y-4 = x+5
Solve for x first
2x+5-5 = x+12-5 Subtract 5 from both sides to eliminate it.
2x-x = x-x+7 Subtract x from both sides to eliminate it.
x=7 Now, substitute 7 for x in y-4 = x+5 to solve for y.
y-4 = (7)+5
y-4 = 12
y-4+4 = 12+4 Add 4 to both sides to eliminate it.
y = 18
Finally, we can substitute 7 for x and 18 for y in all equations to see the lengths of each side.
(18)-4=14 The length of each of the two shorter sides is 14.
2(7)+5=19 The length of each of the two longer sides is 19.
Using the quadratic formula
