If 2 plus 3 equals 10and 7 plus 2 equals 63and 6 plus 5 equals 66and 8 plus 4 equals 96 then 9 plus 7 equals?
144 Formula: c= (a2)+(ab)
How do you solve a to the 3rd power plus b to the 3rd power divided by a plus b?
(a3 + b3)/(a + b) = (a + b)*(a2 - ab + b2)/(a + b) = (a2 - ab + b2)
Ab plus bc equals bc plus ab what property is this?
Commutativity.
What property of equality is if ab plus cd equals ef plus cd then ab equals ef?
The existence of the additive inverse (of ab).
What does ab equals 1a plus 1B plus ab equal to?
ab=1a+1b a is equal to either 0 or two, and b is equal to a
If 2 plus 3 equals 10and 7 plus 2 equals 63and 6 plus 5 equals 66and 8 plus 4 equals 96 then 9 plus 7 equals?
144 Formula: c= (a2)+(ab)
How do you solve a to the 3rd power plus b to the 3rd power divided by a plus b?
(a3 + b3)/(a + b) = (a + b)*(a2 - ab + b2)/(a + b) = (a2 - ab + b2)
If ab plus bc equals ac then ac equals ab plus bc?
yes because ab plus bc is ac
What does ab plus ab equals?
2ab
If a2 plus b2 plus c2 - ab - bc - ca equals 0 then prove a equals b equals c?
a2 + b2 + c2 - ab - bc - ca = 0 => 2a2 + 2b2 + 2c2 - 2ab - 2bc - 2ca = 0 Rearranging, a2 - 2ab + b2 + b2 - 2bc + c2 + c2 - 2ca + a2 = 0 => (a2 - 2ab + b2) + (b2 - 2bc + c2) + (c2 - 2ca + a2) = 0 or (a - b)2 + (b - c)2 + (c - a)2 = 0 so a - b = 0, b - c = 0 and c - a = 0 (since each square is >=0) that is, a = b = c
Ab plus bc equals bc plus ab what property is this?
Commutativity.
A plus B equals AB?
No. A times B = AB
What property of equality is if ab plus cd equals ef plus cd then ab equals ef?
The existence of the additive inverse (of ab).
What is the property that says ab plus c equals ab plus ac?
associative property
If ac plus cb equals ab and ac equals cb then the point c is?
the midpoint of AB.
If you know that AB plus B equals C what is the conclusion?
C minus B equals AB
What is the formula of a cube plus b cube?
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
