Thanks for the help!

Thank you for the explanation!

Sorry for late resopnse... but thank you!

Here's a start...

In the equation 3a + 4b = 7, you can multiply through by 3 to get 9a + 12b = 21.

Next, in the equation 6a + 4b = k - 3a - 8b you can start by simplifying to 4a + 8b = k.

Notice that all the numbers will be a factor of 9; no matter what x is, under certain conditions it will be a difference of multiples of 9.

Have you tried using the formula- \(d=st\) (or d=rt, whatever you want to call it); distance=speed*time.

X = 0

1+1/x=0

x+1=0

x=-1

1+1/(1+1/x) = 0

1 + 1/x + 1 = 0

2+ 1/x = 0

2x +1 = 0

2x = -1

x = -1/2

0+(-1)+(-1/2)=-3/2

10 and 2 o'clock.

The numerical part is 4*8=32.

Thank you CPhill!

TYSM!

I would recommend you start by finding the angle of the n-sided polygon which is 360-90-120-60 = 90 degrees. Since a square is the only regular n-sided polygon with angles of 90 degrees, we know that n = 4.
