The volume of a rectangular prism is (x4 + 4x3 + 3x2 + 8x + 4), and the area of its base is (x3 + 3x2 + 8). If the volume of a r

ectangular prism is the product of its base area and height, what is the height of the prism?

Dividing the volume by the base area, you find the height to be ...
\frac{x^{4}+4x^{3}+3x^{2}+8x+4}{x^{3}+3x^{2}+8}=x+1-\frac{4}{x^{3}+3x^{2}+8}

The height of the prism is x+1-\frac{4}{x^{3}+3x^{2}+8}

Solution:

Volume of Rectangular Prism = x^4 + 4 x^3 + 3 x^2 + 8 x + 4

Area of Base of Prism = x^3 + 3 x^2 + 8

As Given:

→→Volume of Rectangular Prism = Base Area ×  Height

→Height of Prism = \frac{\text{Volume of Rectangular Prism}}{Base Area}

→Height of Prism = \frac{ x^4 + 4 x^3 + 3 x^2 + 8 x + 4}{x^3+3 x^2+8}

                  =\frac{(x+1)(x^3 + 3 x^2 +8) - 4}{ x^3+3 x^2+8 }\\\\=(x + 1)- \frac{4}{x^3+3x^2+8}

15-29=
Dominik [7]

Answer:

15-29= -14

(I need the explanation most importantly)

14+(-4) - 8 =10-8=2

(Explanation please)

-8.4 - (19.5.) = - 27.9, (just add them to each other and write -, because both have - in front of them)

(Explanation)

-15 + 8 - (-19.7) = - 7+19,7=12,7 (there is + and - so it will became - 7, and at next there is two - which will turn them into +)

(Explanation)

29.45 - 56.009 - 78.2=−104,759 (all you have to is to put them all together, and than make it 29.45 less, writing - in front of them)

(Explanation)

LAST ONE

45.9 - (-9.2) + 5= 45.9+9.2+5=55.1+5=60.1 (because when there is 2 minus next to each other it will became plus)

HURRY!!!!<br> What is the equation of the line shown in this graph?
zalisa [80]

Answer:

x = - 2

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

Where c is the value of the x- coordinates the line passes through.

The line passes through (- 2, - 3) and (- 2, 2)

Both of these points have an x- coordinate of - 2, thus

x = - 2 ← equation of line
