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
Answer:
hours.
Step-by-step explanation:
Sean read of a book in hours.
We are asked to determine the time that Sean requires to read of this book.
If the rate of reading the book is assumed to be constant, then we can use the unitary method to find the answer.
Now, Sean reads of a book in hours.
So, Sean reads the total of the book in hours.
Hence, Sean reads of this book in hours. (Answer)
Find the area
the area=length times width=16 times 2=32 square inches
32 times amount charged per square inch=32 times 18=576 cents
costs $5.76
3 x 11= 33, 3 x 13 = 39, 39 & 12 x 3= 36
