Answer: OPTION D.

Step-by-step explanation:

You have the expressions given in the problem:

\frac{2}{2x+3}*\frac{9}{x}

To find the product of both expression you must multiplicate them.

You must multiply the numerators of both expression and the denominators of both expression.

Keeping the above on mind, you obtain that the product is:

\frac{2*9}{(2x+3)x}

 \frac{18}{2x^{2}+3x}

The manufacturer of a weight-training bench spends $15 to build each bench and sells them for $32. The manufacturer also has fix
nasty-shy [4]

Answer:

Step-by-step explanation:

C(x) = 15x + 25,500....cost function

R(x) = 32x .....revenue function

break even point (when they are equal)....so set them equal and solve for x

15x + 25,500 = 32x

25,500 = 32x - 15x

25,500 = 17x

25,500 / 17 = x

1500 = x.......so the break even point is when 1500 benches are sold

15x + 25,500 =                                   32x =

15(1500) + 25,500                              32(1500) =

22,500 + 25,500                                48,000

48,000

and after selling 1500 benches, they will both equal $48,000

Work out the number of sides tile A has.<br> Both tile A and tile B are regular polygons
finlep [7]

Answer:

12

Step-by-step explanation:

since tile B is a regular polygon means it is an equilateral triangle. The angle inside B would be  60.

(360 - 60)/2 = 150 (interior angle of tile A)

180 - 150 = 30 (exterior angle of tile A)

therefore number of sides = 360 /30 = 12
