The answer is A. You multiply each side by (b/2)^2. B is 4. 4 divided by 2 squared is 4. To make it the same equation squared, you factor it to (x+2)^2. You have to also add the (b/2)^2 to 12 so 12+4=16

Giving up al my point for this question
never [62]

Answer:

The mistake there is the expression shown is not in PEMDAS.

<em>PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.</em>

Step-by-step explanation:

1 + 4 x 9                    4 x 9 = 36

1 + 36                        36 + 1 = 37

37

Always remeber to use multiplication first!
