<u>Answer:</u>
The correct answer option is b. 560 units.
<u>Step-by-step explanation:</u>
We are given a prism with a base area of 40 square units and a height of 14 units.
We know the formula for the volume of the prism:
<em>the volume of a prism = Bh</em>
where <em>B</em> is the base area of the prism; and
<em>h</em> is the height of the prism.
Substituting the given values in the formula to get the volume:
Volume of prism = 40 x 14 = 560 units
The given relation is
n·(3n-7) = 20
In standard form, this is
3n² -7n -20 = 0
(n -4)(3n +5) = 0
n = 4 or -5/3
The number is -5/3.
