You reverse the inequality symbol if you divide or multiply by a negative number in order to solve the inequality.

If the number is bigger so say I had 50 > 45 if 50 were put on the other side so it would be 45> 50 you would reverse it because that makes no sense

Answer:

12x³ - 3x

Step-by-step explanation:

Given 

f(x) = x and g(x) = 4x² - 1

Now, 

3 f(x) * g(x) 

= 3 * x (4x² - 1)

= 3x ( 4x² - 1 )

= 12x³ - 3x 

Hope it will help :)

What is the area of the sector a.) 10π cm^2b.) 16π cm^2c.) 40π cm^2d.) 64π cm^2

Natalija [7]

Answer:

C. 40π cm²

Explanation:

• The central angle of the sector = 225 degrees

• The radius of the sector = 8cm

For a sector of radius r and central angle θ, we calculate the area using the formula below:

$\text{Area}=\frac{\theta}{360\degree}\times\pi r^2$

Substituting the given values, we have:

$\begin{gathered} \text{Area}=\frac{225}{360}\times\pi\times8^2 \\ =\frac{5}{8}\times64\times\pi \\ =5\times8\times\pi \\ =40\pi cm^2 \end{gathered}$

The area of the sector is 40π cm².
