Answer:

B. Division

Subtraction is closed for polynomials subtracting two polynomials will result in another polynomial. Same goes with multiplication. However, if you divide polynomials, you are able to get a result that is not always a polynomial. Therefore, division is the answer.

Answer:

B. 126 degrees

Step-by-step explanation:

lets say the angle is x

the equation we have here is the 8th graders divided by the total number of students is equal to x divided by 360 degrees since a circle has a 360 degree angle.

The equation is:

350/1000=x/360

in number form.

350/1000= 0.35 = 35%

so now we know x/360=35%

126/360=35%

so the answer would be 126 degrees.

How to solve x^2&gt;4x+3
Papessa [141]
Treat this as you would the quadratic equation x^2 - 4x - 3 + 0.   Solve this by completing the square:

x^2 - 4x + 4 - 4 - 7 = 0

(x^2 - 4x + 4) = 11

    (x-2)^2 = 11, and so x-2 = plus or minus sqrt(11).

Graph this, using a dashed curve (not a solid curve).  Then shade the coordinate plane ABOVE the graph.
