I don't like dividing polynomials so I'm going to set x=1 and try them out.

(1-2-14+3)/4 = -3

Of the choices, only D gives -3 when x=1

~~~~~~~~~~~~~~~~~~~~~~

That's as much test-taking as math. If we were to divide

x^2 - 5x + 1
-------------------------------
x + 3 | x^3 - 2x^2 - 14x + 3
x^3 + 3x^2
-5x^2 - 14x
5x^2 + 15x
x + 3
x + 3

More work, still choice D

OverLord2011 [107]

The length of the diagonal of the deck can solved using the pythagorean theorem because the diagonal the sides of a rectangle will form a right triangle. pythagorean theorem states that
C^2 = B^2 + A^2
where C is the hypotenuse or the diagonal of the rectangles
B and A are the sides of the rectangle

C^2 = 10^2 + 23^3
C^2 = 629
C = 25.08 ft

Translate the phrase into an algebraic three dollars more than twice the cost of a bowl of soups 2+3

Softa [21]

Answer:

3+2c

Step-by-step explanation:

To translate the phrase into an algebraic expression, you have to analyze the information provided. Three dollars more than twice the cost of a bowl of soups means that given that c is the costs of a bowl of soup, you have to multiply c for 2 as the phrase says twice the cost. Also, it says three dollars more which means that you have to add 3. According to this, the expression is: 3+2c.
