Answer:

Choice C)

x^2 - 2x + 4 - 12/(x+2)

$x^2 - 2x + 4 - \frac{12}{x+2}$

====================================================

Explanation:

To see how I got that answer, I have provided two attached images below. One of them shows the polynomial long division. The other shows synthetic division. Both are valid options to get to the same answer.

For each method, I used 1x^3 + 0x^2 + 0x - 4 in place of x^3 - 4 so that the proper terms could align.

Triangle ABC is formed by two parallel lines and two other intersecting lines. Find the measure of each angle A, B, and of the t

Mamont248 [21]

Answer:

A = 61°

B = 72°

C = 47°

Step-by-step explanation:

Well, first of all, we can see that:

$61^{\circ}+47^{\circ}+B^{\circ}=180^{\circ}$

So, we can find angle B.

$B=180^{\circ}-47^{\circ}-61^{\circ}$

$B=72^{\circ}$

Now, we can see to that angle C is just 47°

Finally, we know that the sum of all angles in a triangle is 180°, so we have:

$B+A+C=180^{\circ}$

$A=180^{\circ}-47^{\circ}-72^{\circ}$

$A=61^{\circ}$

I hope it helps you!

How would I do this plz help

Answer:

273 m^2

Step-by-step explanation:

Firstly, you should find the area of the triangle. Remember that the formula for a triangle's area is (Base x Height) ÷ 2

Therefore,

11 x 14 is 154

154/2 = 77 m^2

Then, we find the area of the square which is just Base x Heigh

14 x 14 is 196m^2

And finally, we just add the two

77 + 196 = 273 m^2

The reason it's not m^3 is because we're not dealing with a third dimensional figure.

Btw, ^ means to the power of.

mandy is on a bus that is traveling at a constant speed of 60 miles per hour how far will she travel in 3 1/2

tekilochka [14]

3 and a half hours i assume. so, 60 times 3 is 180, then divide by 2 to get your half, which is 30 now add that to 180. You have 210. She will travel 210 miles in 3 and a half hours. :)
