12−7=13(−12) what is this i need help

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

the best estimate is 3 because   8 can only go into 24 3 times

(−$11) ⋅ 12

deductions are negative and there are 12 months in a year
