AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1
Answer:
Oh yeah I don’t know not one bit since this picture is stupidly low
Step-by-step explanation:
Get. A better camera
Seth traveled 1mi/57.1s
you need to convert mi/s to mi/h
we need to found how many seconds are in an hour (3,600)
so 3,600/57.1=63.047
63.047mi/h
63mi/h (rounding)
The line slopes downward. More specifically, as x increases, y decreases. Since x is the number of hours trained and y is the mile time, this must mean that the more Mario trains, the shorter his mile time gets.
