Answer:

Step-by-step explanation:

Discount = 15% of 45

=\frac{15}{100}*45\\\\=\frac{675}{100}=6.75

= $6.75

Price of the video game = 45 - 6.75 = $38.25

Tax = 7%of 38.25

=\frac{7}{100}*38.25\\\\=\frac{267.75}{100}=2.6775

Price paid by Fatima for the video game = 38.25 + 2.68 = $ 40.93

The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is th
antoniya [11.8K]

Answer:

The answer is 6x^{3} +39x^{2}+54x

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = x+2

Width (w) = 3x

Height (h) = 2x+9

By substituting these values to the equation above,

Volume of the rectangular prism = (x+2)*3x*(2x+9)

                                                      =(3x^{2} +6x)*(2x+9)

                                                      =6x^{3} +27x^{2} +12x^{2} +54x

                                                      =6x^{3} +39x^{2}+54x

Therefore,

The answer is 6x^{3} +39x^{2}+54x
