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
2x²-19x-33=0
(2x-22 )(2x.+3 ) = 0
(x-11)(2x+3)=0
x-11=0 implies x = 11
2x+3=0 implies x = -3/2
