2x^4 + x^3 - 5x^2 + 3x - 11.
the answer is c.
the identity property of addition is a number (in this case, 61) plus 0 equals 61. this shows that the number doesn't change.
i hope this ! : -)
c is the final : )
assuming our initial temperature in fahrenheit is 32 (celsius would be 0)
if we increase by 10 degrees celsius :
f= 32 + 1.8(10)
f= 32 + 18
the final temperature would be 50 degrees f (celsius 10), but there would have been an increase of 18 degrees f for the 10 degree change in c
