Rounding 1.49 to the nearest tenth would make it 1.50

As a fraction 0.50 is 1/2 so 1.50 becomes 1 1/2

Answer:

3x²+4x-2

Step-by-step explanation:

$\frac{x+2}{2}$ - $\frac{x+1}{3x}$ are not like terms. To make them like terms, you have to multiply the first fraction by 3x, and the second by 2.

This makes it $\frac{3x(x+2)}{6x}$ - $\frac{2(x+1)}{6x}$ , which can be expanded to $\frac{3x^{2}+6x}{6x}$ - $\frac{2x+2}{6x}$ .

This can be simplified to $\frac{3x^{2} +4x-2}{6x}$ .

The numerator is therefore 3x²+4x-2.
