30% chance because 50+20=70 and 100-70=30. Since 30% is below 50%, I would say not likely.

Step-by-step explanation:
Given the upper-left coordinates on a rectangle as (-5, 6), and the upper-right coordinates as (-2, 6), the distance between the two coordinates will be equal to the length of one side of the rectangle. Using the formula for calculating the distance between two points as shown;
D = √(x2-x1)²+(y2-y1)²
The the upper left coordinates be A (-5, 6) and the upper right coordinates be B(-2, 6).
AB = √(-2-(-5))²+(6-6)²
AB = √(-2+5)²
AB = √3²
AB = 3 units = Breadth of the rectangle
Give the perimeter of the rectangle to be 16 units, we can get the length of the rectangle using the formula;
Perimeter of a rectangle = 2(L+B)
16 = 2(3+L)
16 = 6+2L
10 = 2L
L = 5units
The length of the triangle is 5units
Find the diagram of the rectangle on the coordinate plane in the attachment below.
In mathematics, when you are presented with multiple operations in one equation, you follow the PEMDAS rule. This rule assigns which operation should be the first priority. The P means parenthesis. So, any expression inside the parenthesis should be calculated first. This is followed by Exponent(E), Multiplication (M), Division (D), Addition (A) and lastly, Subtraction (S). Technically, when all you have left is addition and subtraction, priority doesn't matter because of associative property.
Step 1: Nothing has change. Blake just copied the original equation.
Step 2: Blake changed the placing of the parenthesis. As mentioned earlier, you have to prioritize what's inside the parenthesis first. You can't change the position of the parenthesis. It will matter. Good thing, the answer, in this case, does not matter. But this does not apply to all situations.
Step 3: Blake was correct. He prioritize the <span>(− 9.2 − 0.8) term which is equal to -10.
Step 4: Associative property allows you interchange the order of the operations without changing the final answer. This is applicable to addition and subtraction operations. Hence, this was used correctly.
Step 5: Technically, this was correct because addition is prioritized more than subtraction.
Therefore, Blake's error was in Step 2.</span>
