Answer:
B) 3x^3 + 24x^2
Step-by-step explanation:
The volume of a pyramid is 1/3 the product of the base area and the height. The base is square, so its area is the square of the side dimension.
V = (1/3)(3x)^2(x+8) = 3x^2(x +8)
V = 3x^3 +24x . . . . . matches B

f (x)=0
x^2-x-2=0
(x-2). (x+1)=0
x-2=0 x=2

Explanation:
You know that the new employee burned
625
chocolate chips in one hour and that this many chocolate chips represented
25
%
of that day's production.
As you know, percentages are used to express fractions that have
100
as their denominator. In this case, you can say that
25
%
=
25
100
This means that for every
100
chocolate chips baked that day,
25
were burned by the new employee. You can simplify this ratio to get
25
100
=
1
4
→
one chip burned for every four chips baked
To solve this problem you must apply the proccedure shown below:
1. You have:
480r^(5-1)=12.288
480r^4=12.288
r^4=12.288/480
r=(12.288/480)^(1/4)
r=0.4
2. Now, multiply r=0.4 to each term, as below:
480x0.4=192
192x0.4=76.8
76.8x0.4=30.72
30.72x0.4=12.288
Therefore, as you can see, the answer is: 192,76.8,30.72
