For an equilateral triangle, all sides must have the same length. This means the perimeter must be evenly divisible by 3. If we can divide the expression above by 3 then the answer is yes it's possible:
We have just solved for the side length, and can see that the expression is evenly divisible by 3, so an equilateral triangle can be created using this expression for its perimeter by subbing in any whole number for x.
Answer:
B
Step-by-step explanation:
there's no point on x^2 +3 at 4 so x < 4 making it B
Answer:
(-10,-7)
Step-by-step explanation:
Lets start with the equation y>-3x+7
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
Now lets do the equation y<4/5x-2
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
So, the point (-10,-7) is not a solution to the system of equations.
The first set of parentheses is unnecessary, so just drop it.
The second set of parentheses has a negative sign to its left.
To simplify the second set of parentheses, change every sign inside the parentheses. Then combine like terms.

= - x - 2 - 4x - 3
= -x - 4x - 2 - 3
= -5x - 5
