(5x³ + 4x²) - (6x² - 2x - 9)

-1(6x²) -1(-2x) -1(-9) = -6x² + 2x + 9

5x³ + 4x² - 6x² + 2x + 9

5x³ - 2x² + 2x + 9 Choice D.

If you would like to solve <span>(5x^3 + 4x^2) - (6x^2 - 2x - 9), you can do this using the following steps:

</span>(5x^3 + 4x^2) - (6x^2 - 2x - 9) = <span>5x^3 + 4x^2 - 6x^2 + 2x + 9 = 5x^3 - 2x^2 + 2x + 9
</span>
The correct result would be <span>D. 5x^3 – 2x^2 + 2x + 9.</span>

Answer:

$15.6

Step-by-step explanation:

Based on the given information, it is $15.6. However, it never specified how many hours she works a day and how many days of the week she works, so we must assume it is just 624/40.

What is the volume of a sphere with a radius of 4 cm? Use 3. 14 for pi. Round to the nearest hundredth. 50. 24 cm³ 66. 99 cm³ 20

Nimfa-mama [501]

The volume of the sphere is 267. 95 cm³.

<h2>Given </h2>

The radius of the sphere is 4cm.

<h3>What is the volume of sphere?</h3>

The volume of a sphere is the three-dimensional space occupied by a sphere.

The volume of the sphere is determined by the following formula;

$\rm Volume = \dfrac{4}{3} \pi r^3$

Where r is the radius of the sphere.

Substitute all the values in the formula;

$\rm Volume = \dfrac{4}{3} \pi r^3\\\\\rm Volume = \dfrac{4}{3} \times (3.14) \times 4^3\\\\Volume = 4 \times 1.04 \times 64\\\\Volume = 267.95\ cm ^3$
