Answer: C and E
Step-by-step explanation:
The plane starts at 32,460 feet.
It then ascends 1645 feet. Ascending means it's going up higher. So we add.
32,460 + 1645 = 34,105 (C)
From here (34,105 feet) the plane descends by 3/5 of it's height. Descending means it's lowering. So we subtract.
But first we have to figure out how much we are subtracting.
3/5 is equal to .6
Multiply to find 3/5 of current height.
34,105 × .6 = 20,463
So the plane descends by 20,463 feet.
34,105 - 20,463 = 13,642 feet (E)

Combine Like Terms:
=3x2+−5x+x3+2x+4
=(x3)+(3x2)+(−5x+2x)+(4)
=x3+3x2+−3x+4
Answer:
2
Step-by-step explanation:
3lb of the $3.75/lb = $11.25
then if I add 2 of the $1.75/lb mix and divide by the amount of total lbs you get $2.95
