Number 7. Please asap.

7a)

$\frac{n(n - 3)}{2} = 665\\n(n - 3) = 665 \cdot 2\\n(n - 3) = 1330\\n^2 - 3n = 1330\\n^2 - 3n - 1330 = 0\\n = \frac{-(-3) \pm \sqrt{(-3)^2 - 4 \cdot 1 \cdot (-1330)}}{2 \cdot 1} = \frac{3 \pm \sqrt{9 + 5320}}{2} = \frac{3 \pm \sqrt{5329}}{2} = \frac{3 \pm 73}{2}\\n_1 = \frac{3 + 73}{2} = \frac{76}{2} = 38\\n_2 = \frac{3 - 73}{2} = \frac{-70}{2} = -35$

If n is the amount of sides then there's 38 sides in a polygon with 665 diagonals

7b)

We do the same as 7a) but with 406. We get that $n_1 = 30.04$ and $n_2 = -27.04$ . A polygon cant have 30.04 sides

If Carl hangs a picture using 3/8 yard of a wire that is 1 1/8 yards long how much wire will Carl have left

nasty-shy [4]

Answer:

1 yard of wire or 8/8 yard of wire

Step-by-step explanation:

To figure out how much wire he has left you need to take 3 from 11 which equals 8. You do not change the 8 that is behind the 3 or 11. This means you have 8/8 or 1 yard of wire.
