Answer:

D. 29

Step-by-step explanation:

According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], evaluate all expressions inside grouping symbols, take care of the exponents, indices, roots, etcetera, evaluate Division & Multiplication from left to right, then evaluate Subtraction & Addition from right to left [or left to right, as long as you know what you are doing correctly]:

[tex](5 + 1)^{2} - (12 + {3}^{2}) \div 3 = {6}^{2} - (12 + 9) \div 3 = \\ \\ 36 - 21 \div 3 = 36 - 7 = 29[/tex]

I am joyous to assist you anytime.
