H=45d h stands for hours and 45d means 45 minutes per day
The volume of the first cube is (5h^2)^3, while the volume of the second cube is (3k)^3, so their total volume is (5h^2)^3 + (3k)^3. We can use the special formula for factoring a sum of two cubes:
x^3 + y^3 = (x + y)(x^2 - xy + y^2)
(5h^2)^3 + (3k)^3 = (5h^2 + 3k)((5h^2)^2 - (5h^2)(3k) + (3k)^2)
= (5h^2 + 3k)(25h^4 - 15(h^2)(k) + 9k^2)
This is the second of the given choices.
Answer:
D.
Step-by-step explanation:
Solution,
Two dice are thrown.
So we have to find out the total number of outcomes.






The total number of outcomes = 
We have to find out the probability of outcomes that add up to 9.
So, Possible outcomes are;
<u>
</u>
The total number of possible outcomes = 
Now, according to the formula of probability,


Hence the correct option is D)4/36.
Always follow the rules of BOMDAS. (If you don't know them or maybe learned differently tell me).
Firstly multiply 4(1/2) and then substract
8 - 4(1/2)
8 - 2
6
Hope this helps :).
