The answer is (9a3-10) (9a3+10)
When the value of a dependent variable decreases as the value of an independent variable increases, the function is said to be a decreasing function.
If we graph such a function, as x goes from 0 to the right (getting larger), the y value will decrease; we would be able to physically see the graph decrease.

Answer:
46.67 cubic feet
Step-by-step explanation:
The formula for volume of a pyramid is
V = (1/3)Bh where B is the area of the base, and h is the height.
We are givne B = 35 and h = 4. Plug those values in and simplify...
V = (1/3)(35)(4)
V = (1/3)(140)
V = 140/3
V = 46 2/3 cubic feet, which is 46.666667, or 46.67 rounded to the nearest hundredth
1400, as 1200 + 200 = 1,400 and 1600 - 200 = 1400.
