Answer:
Volume = 10a³ + 91a² + 54a - 792
Step-by-step explanation:
In the absence of answer choices, let's find the expression for the volume.
Given: Volume = length×width×height
V = lwh
length =(2a + 11)
width =(5a – 12)
height= (a + 6)
V = (2a + 11)(5a – 12) (a + 6)
Expand the first two brackets using distributive property
V = (10a² -24a +55a - 132)(a + 6)
Collect like terms
V = (10a² + 31a -132)(a + 6)
Expand the two brackets using distributive property
V = 10a³ + 31a² - 132a + 60a² + 186a - 792
Collect like terms
V = 10a³ + 91a² + 54a - 792
The expression that represents the volume of the box = 10a³ + 91a² + 54a - 792
Answer:
18
Step-by-step explanation:
30-60-90 triangles have a set of x values that you can plug your numbers into.
we know that the side length opposite to 30 is x
the side length opposite to 60 is xsqrt3
the side length opposite to 90 is 2x
from this we can gather that y=2x where x=9 therefore y=18
Answer: SECOND OPTION
Step-by-step explanation:
To solve the problem you must:
-Multiply the numerators and the denominators of both expressions:
- Simplify the expression, as you can see below, then you obtain:
Therefore, as you can see, the answer is the second option

Answer: A. 
Step-by-step explanation:
Given : A certain CD-ROM disk can store approximately 
megabytes of information.
1 megabyte = 
bytes
Then, The storage capacity of CD-ROM disk will be :
If an average word requires 14 bytes of storage, then the number of words can be stored :-
Hence, number of words can be stored =
