F(x)=8_-4x-x^3. g(x)=x^2+7x-9. Find f(x)+g(x)
11111nata11111 [884]

(8 - 4x -  {x}^{3} ) + ( {x}^{2}  + 7x - 9) \\  =  -  {x}^{3}  +  {x}^{2}  - 4x + 7x + 8 - 9 \\  =  -  {x}^{3}  +  {x}^{2}  + 3x - 1
(8x - 4x -  {x}^{3} ) + ( {x}^{2}  + 7x - 9) \\  -  {x}^{3}  +  {x}^{2}  + 8x - 4x + 7x - 9 \\  -  {x}^{3}  +  {x}^{2}  + 11x - 9
The answer is either B, and you forgot to put in the ^2 in the answer choice, or C, and you forgot to put an x where there is a _ in the question.

Check the actual question (the one you recieved, not the one posted here) and see where the mistakes are. If f(x) = 8x - 4x - x^3, then your answer is C. However, if B is actually -x^3 + x^2 + 3x - 1, then the answer is B.

A rectangular prism of volume 3200 mm has a rectangular base of 10 mm and width 8 mm. Find the height h of the prism
Orlov [11]

Answer:

40 mm

Step-by-step explanation:

The rectangular prism of a rectangular box. The volume is given by the formula:

<u>Volume of Rectangular Prism</u> = length * width * height

Given Volume = 3200

Length = 10

Width = 8

We need to find height. So we plug in the given information and find the height, in mm. Shown below:

Volume = Length * Width * Height

3200 = 10 * 8 * Height

3200 = 80 * Height

Height = 3200/80

Height = 40 mm

The height (h) = 40 mm
