Solution: We know that:
Paul and Brett went to math class and were given the same expression to simplify. The expression they were given was 6 + 12 divided by 2(3) + 1.
Looking at the solution's by Paul and Brett, we clearly see that the Paul made a mistake at step 3.
6 + 12 ÷ 2(3) + 1
6 + 12 ÷ 6 + 1 Correct
18 ÷ 6 + 1 Incorrect It should have been 6 + 2 +1
According to order of operation's rule, division needs to done before addition.
Therefore, solution by Paul carries a mistake, while the solution by Brett is correct.
<h2>The answer is 20² + 6(9 + 3) = 472</h2>
Use PEMDAS:
P) Parentheses first
E) Exponents (For example, Powers and Square Roots.)
MD) Multiplication and Division
AS) Addition and Subtraction

20² + 6 (9 + 3) = 400 + 6 (12) = 400 + 72 = 472
If you are solving a system of equations by graphing it, the point of intersection makes both equations true! C:
The question is incomplete. Below you will find the missing part of the question.
How many rabbits were there after x years? Write a function to represent this scenario.
rabbits were there after x years.
The function form is
The number of rabbits released each year is 8.
During 0 year, there will be 8 rabbits;
During year 1, the number of rabbits will be 8+8 = 16, i.e. 8×2¹ = 16
Similarly, during the year 2, the number of rabbits will be 16+16 i.e. 8×2² = 32
So, according to the pattern we can say that the function would be
