Draw a vertical line at the number 4 on your x axis positive side which is x=4
Then anything on the left of this line you just created at x=4 will be less than 4. But since your inequality is x less than/equal to 4 it includes 4 as well.
Idk if i'm right (2x - 5) (x + 1)
<span>you need 6 digits, as the possible numbers will run from 000000 to 999999 should use an agency to make above tags</span>
Here's a thing you can do with square roots and fractions:
√ (a/b) = √a / √b . Is that neat or what !
So √(64/25) = √64 / √25 .
We know the square root of 64 . . . that's 8 .
We know the square root of 25 . . . that's 5 .
So √(64/25) = √64 / √25 = 8 / 5 .
But before we walk away from it, we need to remember that the
square root of any number can be either positive or negative.
So both the '8' and the '5' can be either positive or negative.
When you mash that around, you realize that the question has
two answers. They are . . .
<em> + 1.6</em> and <em>- 1.6 .</em>
