A square and a equilateral triangle have the same perimeter the perimeter of the triangles is 12(z-2)cm.the perimeter of the square is 4x cm find the perimeter of each figure by writing and solving an equation for the variable of x. what is the value of x
<h2>SOLUTION</h2>- ➝ 12(x - 2) = 4x
- ➝ 12x - 24 = 4x
- ➝ 12x - 4x = 24
- ➝ 8x = 24
- ➝ x = 3
Therefore, the value of x is 3

Answer as a compound inequality:
Answer in interval notation: [-4, 2)
=============================================
Explanation:
The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.
The lowest point occurs when y = -4. We include this value. So far we have which is the same as
The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that
Combine and
to get the compound inequality
This says y is between -4 and 2, including -4 but excluding 2.
To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.
