Help please!!
Write an equation for the word problem.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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

i have not got your picture clearly so see it once again
