It's 3.01 sorry wrong question please forgive me
Answer:
Age of ben = n years
Age of Chloe = 2n years
Age of Dan = (n - 5) years
Now,
Sum of ben, Chloe and Dan's age = t years
or, n +2n + n - 5 = t
or, 4n - 5 =t
This is the required formula
Answer:
972π cm³
Step-by-step explanation:
Okay so this container is a sphere, so you're going to want to use the volume of a sphere equation V = (4/3) * π * r³. In this case, you've got the diameter (d = 18), so divide by 2 to get r = 9.
So now you have all the variables you need to solve. Substituting those values into the volume equation, you get:
V = (4/3) * π * 9³ = 972π cm³.
the product of 2 times x and the sum of 9 and 5 times the square of x
2x *(9+5x^2)
