The Greatest Common Factor (GCF) is 13.
(3x - 7y)(2x + 9y)
13 * x * y * y
5y - 65xy '5' is a common factor both numbers. Hence 'take it out'. 5(y - 13xy) 'y' is a common factor to both terms, so take it out too!!!! 5y(1 - 13x) Done Factored!!!!!
X4y6
The GCF is 13xy.
If by "What is the answer to", you mean "How do you factor", then we can solve it as follows: x2 + 13xy + 36y2 = x2 + 4xy + 9xy + 36y2 = x(x + 4y) + 9y(x + 4y) = (x + 9y)(x + 4y)
The GCF is 13xy.
The GCF is 13xy.
15xy-2xy-7x+x=13xy-6x
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y^2 or (x + y)^2.
7 + 4x = 34 + x Don't expect answers for homework, but I'll do this one. The rule for ANY math equation is to apply the same operation to both sides including using the same numbers. (operations are +,-,/,*, etc). And you can combine numbers with the same type of variable or lack of (e.g. 2x + 3x = 5x or 2 + 2 = 4 or 5yx + 7xy = 13xy) (7 + 4x) - 7 = (34 + x) -7 // subtract 7 on both sides 4x = 26 + x (4x) - x = (27 + x ) - x // subtract x on both sides 3x = 27 (3x)/3 = 27/3 // divide by 3 on both sides x = 9 check the answer 7 + 4*(9) = 34 + 9 7 + 36 = 43 43 = 43; so correct Writing this is a long form, but do this when you are first learning, then simplify your writing as you figure tricks or can do it in you head.
