I NEED HELP ASAP! Leon evaluated the expression Negative one-half(–4a – 6) + a2 for a = 8. Negative one-half(-4(8) - 6) + 82 Negative one-half (-32-6) + 82 Negative one-half(-38) + 82 Negative one-half(-38) + 16 –19 + 16 –3 Analyze Leon's work. Check all that apply. Leon should have subtracted inside the parentheses before he multiplied. The expression inside the parentheses should be simplified to –26 instead of –38. Leon multiplied 8 by 2 when he should have raised 8 to a power of 2. The multiplication of two negative values in step 4 should result in a positive value. The correct answer should be 83.

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

                                            =
