Which step should richard perform last? Will choose brainliest. Any absurd answers will be reported.

A

Step-by-step explanation:

Our equation is: 9² + 2[(5 + 2)² - 4]. We need to use PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.

The first thing to do is to add the 5 and 2 in the parentheses:

9² + 2[(5 + 2)² - 4]

9² + 2[(7)² - 4]

Then square the 7:

9² + 2[(7)² - 4]

9² + 2[49 - 4]

Do the subtraction operation within the parentheses/brackets:

9² + 2[49 - 4]

9² + 2[45]

Square 9:

9² + 2[45]

81 + 2[45]

Multiply 2 by 45:

81 + 2[45]

81 + 90

Thus, the answer is A.

A

Step-by-step explanation:

9² + 2[(5+2)² - 4]

81 + 2[(7)² - 4]

81 + 2[49 - 4]

81 + 2(45)

81 + 90

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
