I'm pretty sure the area of this triangle is 30 m squared. Can someone please tell me if I am right?

It is 30m.. Because you do 10x6=60 then divide it by 2 which is 20.. and hxb/2 is the formulas so.

Which of the following shows that polynomials are closed under subtraction when two polynomials, (5x2 3x 4) − (2x2 5x − 1), are

Verizon [17]

The closure property under subtraction is shown when the correct

result from the subtraction of polynomials is also a polynomial.

Response:

The option that shows that polynomials are closed under subtraction is; <u>3·x² - 2·x + 5 will be a polynomial</u>.

<h3>How is the option that shows the closure property found?</h3>

The closure property under subtraction for the polynomials is condition

in which the result of the difference between two polynomials is also a

polynomial.

The given polynomials being subtracted is presented as follows;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1)

Which gives;

(5·x² + 3·x + 4) - (2·x² + 5·x - 1) = 3·x² - 2·x + 5

Given that the result of the subtraction, 3·x² - 2·x + 5, is also a

polynomial, we have, that the option that shows that polynomials are

closed under subtraction is; <u>3·x² - 2·x + 5 will (always) be a polynomial</u>.

about 50% of the population of Alaska lives within a 50 mile radius of anchorage. if the total area of Alaska is 586,412 mi.² ab

vredina [299]

So since it is a 50 mile radius around one point, then it makes a circle. You need to find the are of the circle to find out how much land that is. you use the equation A= $\pi$ r². Plug 50 in for r and you get A= $\pi$ 50². 50²=2500. Then you multiply that by 3.14 (rounded number of pi) and you get 7850. So, now you have the total land area, now you need the percent of the total Alaskan land. To do that, you make a proportion. $\frac{7850}{586,412}$ = $\frac{x}{100}$ Then, you cross multiply and get 785,000=586,412x. To find out what x is, you divide both sides by 586,412 and get x=1.3386 % . Hope this helps!!

Answer:

(-2, 3) And you're not a dummy!

Step-by-step explanation:

x + 3(3) = 7 (multiply 3 times 3)

x + 9 = 7 ( subtract 9 on both sides)

x = -2

It already gave you y

y = 3
