Simplify the polynomial (4n² + 3n – 5) − (2n² + 3n<br> -<br> + 6)

Veseljchak [2.6K]

Answer:

2n² + 1

Step-by-step explanation:

Given polynomial:

(4n² + 3n – 5) − (2n² + 3n - 6)

Solution:

Removing parentheses,we obtain

$4n {}^{2} + 3n - 5 - 2n {}^{2} - 3n + 6$

Combine like terms:

$4n { }^{2} - 2n {}^{2} + 3n - 3n - 5 + 6$
$2n { }^{2} + 0 + 1$
$\boxed{2n {}^{2} + 1}$

Done!

Durning the martinez family trip, they drove from home to a ski lodge, a distance of 64 4/5 miles, and then drove an additional

SpyIntel [72]

Answer: $167\dfrac15\text{ miles}$ .

Step-by-step explanation:

Since

$64\dfrac45\text{miles}=\dfrac{64\times5+4}{5}\text{ miles}\\\\=\dfrac{324}{5}\text{ miles}$

$18\dfrac45\text{ miles}=\dfrac{18\times5+4}{5}\text{ miles}\\\\=\dfrac{94}{5}\text{ miles}$

Total distance traveled during the trip = $\dfrac{324}{5}+\dfrac{94}{5}+\dfrac{324}{5}+\dfrac{94}{5}$

$= \dfrac{836}{5}\\\\=167\dfrac15\text{ miles}$

Hence, the distance traveled during their trip was $167\dfrac15\text{ miles}$ .

Select the correct answer. describe the zeros of the graphed function

katrin [286]

Answer:

The zeroes are at (-2, 0), (0, 0) and (2, 0).

The (0, 0) is a double root as the graph just touches the x axis at (0, 0).

The zero at (0, 0) is sometimes referred as x = 0 (multiplicity 2).

I think the duplicate roots are counted as 2 distinct roots but im not sure.

So the answer is either a or c.

Step-by-step explanation:

The zeroes are the points where the graph cuts the x axis.
