3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

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

3+3+3+2*2*2+29*12 = 365
