<span>x + 9 = 2(x - 1)^2
x + 9 = 2(x^2 - 2x + 1)
x + 9 = 2x^2 - 4x + 2
</span>2x^2 - 4x + 2 - x - 9 = 0

In the summer of 2014, the average listing price for homes for sale in the Hollywood Hills was $2,663,995.
Wewaii [24]

Answer:

  • monthly payment: $15,903.61
  • interest: $2,368,664.10

Step-by-step explanation:

a) The loan amount is 90% of the price shown, so is ...

  0.90 × $2,663,995 = $2,397,595.50

The monthly loan payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

  A = $2,397,595.50(0.0525/12)/(1 -(1 +0.0525/12)^(-12·30))

  A = $13,239.61

The monthly escrow payment will be 1/12 of the annual amount:

  0.012 × $2,663,995 / 12 = $2664.00

So, the total monthly payment on the house will be ...

  $13,239.61 +2664.00 = $15,903.61

__

b) The sum of monthly loan payments is ...

  $13,239.61 × 360 = $4,766,259.60

so the interest on the $2,397,595.50 loan is ...

  $4,766,259.60 -2,397,595.50 = $2,368,664.10

A rectangular field has an area of 1,764 m(squared). The width of the field is 13 m more than the length. What is the perimeter
Andrej [43]

Answer:

170m

Step-by-step explanation:

The answer to the above question is letter d which is 170 m. To get the 170 m, kindly check the below solution: 

x^2 + 13x = 1764 so x = -49 and 36, we take 36 as its the positive value. And the other side is 49. Now use 2(l+b) to find perimeter. You get (36+49)*2 = 170
