I need someone really good at math to help me with this question. A house sells for 200,000 and a 6% down payment is made. A mortgage is secured at 4% for 20 years. Do not round intermediate calculations. Find the down payment, amount of mortgage, monthly payment, and total paid investment.

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
