Answer:
22x^2 -10xy + 12x
Step-by-step explanation:
To add and subtract polynomials, combine only like terms. When doing it vertically, stack polynomials and line up the same bases and exponents. Once this is done, simply add and subtract the coefficients.
10x^2 + 12xy + 4x
+ 12x^2 -22xy + 8x
_________________
22x^2 -10xy + 12x
Here we added 10 + 12 = 22, 12 + -22 = -10 and 4 + 8 = 12.
<span>−4.6−(0.4+7.2)
</span><span>−20+(−40)+(−60)
4 and 5 is properties of addition
-80 is your answer

"Per" essentially means "divided by." To find pieces per ounce, divide pieces by ounces.
(252 pieces)/(14 ounces) = (252/14) pieces/ounce = 18 pieces/ounce
30,384 feet difference between the two, since the climber is 29,035 feet above sea level you take a positive 29,035 and a -1,349 due to being below sea level, you add the two together with the equation 29,035+1349=30,384 feet
Answer:
The perimeter is 24 feet :]
