Try 3.14x2= 6.28 im so sorry if its wrong
3/4 of an hour = 45 minutes
45 * 3 = 135 minutes
135 + 45 = 180 minutes
He spends 180 minutes or 3 hours
Im not good in math and this is my first question, my best guess is D
I will investigate tommorow this problem a little bit more... <3
Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))". That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f. hope this helps.
If u man just simplifying it
B^8+c^10 (just add exponents)
