(a + b)/(a - b) = (c + d)/(c - d) cross multiply
(a + b)(c - d) = (a - b)(c + d)
ac - ad + bc - bd = ac + ad - bc - bd
-ad + bc = -bc + ad
-ad - ad = - bc - bc
-2ad = -2bc
ad = bc that is the product of the means equals the product of the extremes
a/b = b/c

What does 9k plus 4b minus 7 minus 5k plus b equals?
That depends what the values of k and b are.
In matrix multipliccation when does A plus B times A minus B equals A squared minus B squared?
All the time
What is communtative property?
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators
Calcuate the quantity of x and it's maximum error if x equals 6a plus 4b where a equals 40 tolerance is plus or minus 2 and b equals 20 plus or minus 2?
320 tolerance +/- 20 ? Did I get it right?
Can you help me simplify 20a plus 14-8a-7 and b plus 6b-2b?
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
What are the terms of a quadratic equation?
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
What does 9k plus 4b minus 7 minus 5k plus b equals?
That depends what the values of k and b are.

If you know that AB plus B equals C what is the conclusion?
C minus B equals AB
If a equals 3 and bequals minus 5 then a minus b equals?
If a equals 3 and b equals minus 5 then a minus b equals what

What if you have the equation of y-1 equals x and you want it to b in y equals mx plus b?
the y-1 is a minus .
Find the numerical value for each symbol... a plus a plus a plus b equals a plus a plus b plus b plus b equals c plus c c minus a equals 6 What is the answer to this?
A=8 B=4 C=14 Yes, I know I'm a genius. Mak - the all knowing one. MWAHAHAH!

If a minus b equals c then what does b minus a equals?
a - b = c -(a - b) = -c b - a = -c
Can you help me simplify 20a plus 14-8a-7 and b plus 6b-2b?
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
If vector c equals vector a plus vector b under what circumstances does c equal a minus b?
When b is zero.
