lianna [129]

Answer:

  $1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

  A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

  A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.

X2+2x-35<br> How can you simplify 2+48-21
SSSSS [86.1K]

Answer:

x2-2x-35

Final result :

 (x + 5) • (x - 7)

Step by step solution :

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  x2-2x-35

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  -35

Step-1 : Multiply the coefficient of the first term by the constant   1 • -35 = -35

Step-2 : Find two factors of  -35  whose sum equals the coefficient of the middle term, which is   -2 .

     -35    +    1    =    -34

     -7    +    5    =    -2    That's it

Step-by-step explanation: 2+48-21

Final Result :

     29
