Line segment B
multiply 3.28 by 2
=6.56ft
Are there any decimals? Round to one digit: 7729 expressed in 1 digit = 8x10^-3
No
lets say a and b are positive numbers
that means -a and -b are negative
if you make the difference between these to it'd be
-a-(-b) which means -a+b, and if b>a then the difference is positive
The possible ordered pairs whose product will be negative (less than zero) are,
![(x,-y) \: or \: (-x,y)](https://tex.z-dn.net/?f=%28x%2C-y%29%20%20%5C%3A%20or%20%5C%3A%20%20%28-x%2Cy%29%20)
That is all these products will give us,
![- xy](https://tex.z-dn.net/?f=%20-%20xy)
![-xy< 0](https://tex.z-dn.net/?f=%20-xy%3C%200)
The point must be in the second quadrant where x is negative and y is positive.
Or in the fourth quadrant, where y is negative and x is positive.
