Answer:

m = 2.5

Step-by-step explanation:

Add 0.8 m to both sides, obtaining 0.8m + 0.8m - 4, or 1.6m - 4 = 0.

Now add 4 to both sides.  Result:  1.6m = 4, and m = 4/1.6 = 2.5 = m

find the volume of a rectangular prism if the length is 3x^2, the width is 2xand the height is x^2+3x+5
nevsk [136]

You are given the length of a rectangular prism of 3x^2, width of 2x and height of x^2 + 3x +5. You are required to find the volume of a rectangular prism. Using the equation V = l x w x h, we multiply the three dimensions.

V = l x w x h

V = (3x^2)(2x)( x^2 + 3x +5)

V = 2x (3x^4 + 9x^3 + 15x^2)

V = 6x^5 + 18x^4 + 30x^3

The volume of the rectangular prism is 6x^5 + 18x^4 + 30x^3.
