Hello from MrBillDoesMath
Answer: 12, 9
Discussion:
Let x be the first number and y the second number. The form the problem statement:
x + y = 21
x - y = 3
Add the two equations. This gives:
(x + x ) + ( y-y) = 21 + 3 =>
2x + 0 = 24 =>
x = 12
Since x -y =3, substituting in the value of x gives, 12 - y = 3 so y = 9
Thank you,

-2 + 3b = 5b - 2(2b + 3) Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6 Combine like terms
-2 + 3b = b - 6 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6 Combine like terms
-2 + 2b = -6 Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2 Combine like terms
2b = -4 Isolate b by dividing both sides by 2
b = -4/2 = -2
Answer b = -2
Answer:
A Quartic Trinomial is a polynomial whose highest power of the variable is four.
That being said, I believe it is A. 2x^4-2x+6

Answer:
you'll go over 2 and then go up 2 to get your 2x and 2y
What is the centripetal force keeping the Earth in orbit?
I found how far the earth travels in one year (340,000,000), The Earths Tangential velocity (29814 m/s), and the centripetal acceleration of the earth (5.928e-3 m/s^2), but what is the centripetal force keeping the earth in orbit?
