So the sides ML and MN are exactly the same. Your equation would look something like this... 3x = x + 10 You first subtract x from both sides to isolate the variable. 2x = 10 Divide 2 from both sides. x = 5 5 is the length of MN. I hope this helps love! :)
6.12% compounded monthly equals 0.0612/12, or 0.0051 added monthly. So, $3500 invested for 4-1/2 years is: 3500 x (1.0051)^(48+6)=1.3161x3500=$4606.48 ☺☺☺☺
