So first of all you know that one side is 14cm and the other side is 6cm
What you would do is: 14-6=???
Your answer should be: 8cm
Yes because 3×2= 6 , 3×5= 15, 15 + 6 = 21
Answer:
where is the function? where are the equations?
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.
