If the point representing the number x on the number axis is on the left side of the origin, the result of simplifying │ 3x + √ x │ is?
The result of simplifying │ 3x + √ x │ is (- x-3x) = - 4x
On the number axis, the point of X is on the left side of the origin. Simplify the square of | 3x | + √ X
You don't have to draw the number axis, just simplify it
On the number axis, the point of X is on the left side of the origin, so X
