Perimeter = 2*(length +width)
perimeter = 2*(3x + (3x +(2x+6)))
.. = 2*(3x +3x +2x +6)
.. = 2*(8x +6)
perimeter = 16x +12

If x=3, the perimeter is 16*3 +12 = 60 inches.

The Hughes purchased a new condo for $ 1,000,000. at 8 % for 30 years. What is the monthly payment?
viktelen [127]
We know that

P = A/D
Where,
P = monthly payments,
A = Total amount =$1,000,000
D=[(1+r/12) ^{12*t}-1]/[(r/12)*(1+r/12)^{12*t}]

in this problem

t=30 years
r=8%----> 0.08

D=[(1+0.08/12) ^{12*30}-1]/[(0.08/12)*(1+0.08/12)^{12*30}] =136.2835

P=1000000/136.2835-----\ \textgreater \  P=$7337.65


the answer is
$7337.65
