Ответ:
If the value of c is negative, you would need zero pairs to model the factorization of the polynomial. The x-tiles on the board determine what the constants are in the factors. The product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. Opposite signs on the constants will result in a negative value for c when multiplying the factors.

Ответ:
The second option ,$ 352.95 is correct
Step-by-step explanation:
The total cost of the home is the list price of $89,000 plus the sales tax of 4.2%
total cost=$89,000+($89,000*4.2%)=$92,738
loan amount=total cost-down payment=92738
-3000=$89738
APR is 4.75% since they have an excellent credit score
interest for first month=89738
*4.75%/12=$ 355.21
Principal payment in first month=total payment-interest=925.67- 355.21 =$570.46
principal left after first payment=$89,738
-$570.46=$89,167.54
second month interest payment= 89,167.54*4.75%/12=$ 352.95
The correct option is $ 352.95 which is the second option
