Answer:
Step-by-step explanation:
x^2+8x-3=0 (move constant to other side by adding 3 to each side)
x^2+8x=3 (halve thr linear coefficient, square it and add to each side, (8/2)^2=16)
x^2+8x+16=3+16 (now the left side is a perfect square)
(x+4)^2=19 (now take the square root of each side)
x+4=+-(19^(1/2)) (finally subtract the constant to isolate x by itself)
x= -4+-(19^(1/2))
x=negative four plus or minus the square root of nineteen
So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out.
So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31

Answer:
there all the same variables so it'll be 6y
The minimum happens at x = -b/2a
x = -30 / 2(3) = -30/6 = -5
Now replace x in the equation with -5 and solve:
3(-5)^2 + 30(-5) +27 = 75 - 150 + 27 = -48
The minimum is at (-5,-48)
