The answer is e none of the above
Aren’t there only 2? Because of the squared exponent? I’m not fully sure
They are both right because the first expression is the perimeter but expanded in terms of length.The second expression is shortened to be a factor expression but they both represent the length.
The benefit of the first one is you can see how it’s expanded and plug the numbers in and the second one is more easy to plug in the numbers with ease.
<u>PEMDAS</u>
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.
First, divide 3 from both sides of the equation:


Next, isolate the variable, x, by rooting both sides of the equation:

x = ±4
C) ±4 is your answer.
