Given:
AC = √(-2-3)² + (6-2)²
AC = √ -5² + 4²
AC = √ 25 + 16
AC = √41
AC = 6.40
I am assuming that the triangle is an equilateral triangle. This means that all sides are equal.
AC = AB = BC
Perimeter = 6.40 * 3 sides = 19.20
The z-score is the number of standard deviations away from the mean. We first subtract the actual score from the mean, then divide the difference by the standard deviation. In this case, our actual score is 13, so we subtract from the mean of 16, then divide by the SD of 2
(13 - 16) / 2 = -1.5
The simplified form of the expression is -10x - 16
<h3>Factorizing expressions</h3>
Given the expression -2(5x + 8)
In order to factorize the expression, we will use the distributive property. Distribute -2 over 5x and 8 to have:
Step 1: Distribute -2 to 5x and 8
-2(5x + 8) =-2(5x) -2(8)
Simplify
-2(5x + 8) = -10x - 16
Hence the simplified form of the expression is -10x - 16
