1) Let's look at what we know and Create an equation:

Perimeter: 6x

Side A: x + 3

Side B: 2x + 4

Side C (Unknown): Let's call this 'a'.

Because you find the perimeter of a figure by adding the lengths of all its sides together, our equation would be (the parentheses are only there to help you visualize):

(X + 3) + (2x +4) + (a) = 6x

(Side A+Side B+Side C = Perimeter)

2) From here, we combine like terms:

3x + 7 + a = 6x

3) Isolate the variable in which we are solving for (a):

<u>a = 3x - 7</u>

Since we cannot simplify any further, the length of the missing side is <u>3x - 7</u>.

Well, first, the equation that you are looking for is Y = MX + B. To find B, look at the first dot on the Y-axis. It starts at positive 3, so, you know your equation will end with +3. Next, to find MX, start at the either dot, and find the Rise/Run. In this particular equation, the rise is 1, and, the run is -2, because it's going backwards (negative line). Meaning, the line's equation would be, f( x )= -1/2x + 3.

Ruby is visiting a wildlife center to gather information for her term paper. The center has a circular pond with a diameter of 2
Anton [14]
Well , the diameter means a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. The area means what the extent or measurement of a surface or piece of land. So area means inside so all you need to do is  just to divide each side by knowing what 20/4 is and that = 5 meters
