Okay, so we're going to do like this.
00:03
It says it wants us to do number 10.
00:04
So we'll do maybe 10 and 11, because we're going to say which one to do.
00:07
So we're given x plus 5 greater than 7 or x minus 3 is less than negative 7.
00:14
Well, if we went ahead and subtract it on this side, we get x is greater than 2.
00:18
And if we add on this side, this is maybe 10, then we get x is less than negative 4.
00:25
So just put these together, x is bigger than 2, but less than negative 4.
00:29
So negative infinity to negative 4.
00:31
And then union it with two bigger than infinity.
00:34
Those are solutions for 10.
00:37
11, find the values of x and satisfy this inequality.
00:39
Well, we're just going to go ahead and foil these out.
00:42
Multiply them together.
00:45
So when i do that, i get 15x squared...
