We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
<u>The function that represents the </u><u>volume</u><u> of the chest is </u><u>40.</u>
What is a volume simple definition?
- The amount of space occupied by a three-dimensional figure as measured in cubic units (as inches, quarts, or centimeters) cubic capacity.
- The amount of a substance occupying a particular volume.
When the Area of rectangular chest:
A(x) = 20√x /3
⇒ Volume of chest = Base area x Height
Therefore:
(X + 6) × 20√x /3
(20x√x /3 ) + (20 × 6√x/3)
(20x√x /3 ) + (20 × 2 × 3√x/3)
(20x√x/3) + 40√x
Therefore, the correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.
