Which of the following shows the division problem below in synthetic division form?

MissTica

Answer:

Choice D

Step-by-step explanation:

Given division problem is $\frac{5x^2+9x-6}{x+2}$

Now we need to find about which of the given choices shows the division problem below in synthetic division form.

To convert into synthetic division form, we set denominator =0 so we get

x+2=0 or x=-2

Hence we divide by -2

Now collect coefficients of numerator for the dividend part

Coefficients of $5x^2+9x-6$ are 5 9 -6

Hence correct choice is D

Find the area of the shaded regions:

Crank

First, we'll find the area of the large section, including the smaller section that is white.

Area of a circle: pi x r^2

A = pi x 7^2

A = 49pi x 120/360

A = 49/3 pi cm^2

Now, we'll find the area of the small section.

A = pi x 3^2

A = 9 pi x 120/360

A = 3pi cm^2

All that's left to do now is subtract.

49/3 pi - 3 pi

40/3 pi cm^2

(or 13 1/3 = 13.33 cm^2)

Hope this helps!
