Answer:

n^2+27 and 3n-1

Step-by-step explanation:

n is a number.

a number squared is n^2

27 more than a number squared is n^2+27

n is a number.

three times a number is 3 times n, or 3n

one less than that is 3n-1

Hope this answer helped! :)

How does 3x = 4(x-2.25) = 9. Wherethe hell is everyone getting a 9?!?! At a bargain store, Tanya bought three items that each co
andrew11 [14]

Answer:


Step-by-step explanation:

Here is how to get 9:

3x = 4(x - 2.25)

Solve 4(x - 2.25)

3x = 4x - 9

Move the variable to the left side and change it's sign

3x - 4x = -9

Combine like terms

-x = -9

change the signs

x = 9

There ya go! I hope this isn't too confusing!
