Distributivity - In mathematics, and in particular in abstract algebra, distributivity is a property of binary operations that generalises the distributive law from elementary algebra. For example: In the left-hand side of the above equation, the 2 multiplies the sum of 1 and 3; on the right-hand side, it multiplies the 1 and the 3 individually, with the results added afterwards. Because these give the same final answer (8), we say that multiplication by 2 distributes over addition of 1 and 3. Since we could have put any real numbers in place of 2, 1, and 3 above, and still have obtained a true equation, we say that multiplication of real numbers distributes over addition of real numbers. Given a set S and two binary operations · and + on S, we say that the operation · Notice that when · is commutative, then the three above conditions are logically equivalent. In practice, the distributive property of multiplication (and division) over addition is lost around the limits..

What should the sum of your frequency distribution be?Walks students through creating a grouped frequency table. Note that the finished result would have only two columns: The apparent limits (eg, 80 - 99), and the percent (eg, 15%). The frequency and relative frequency columns would not be part of the finished product for a grouped percentage table... they are in this case just intermediate steps.
Question : x+2 / 6 = x+2 / x
The sum of these solutions is:
A. -4
B. 6
C. 4
D. 0
It looks better if you actually write it down in fraction form. Can you please tell me how you solve a problem like this step by step? Thanks!
Answer : Cross multiply since this is a proportion you can cross multiply x(x + 2) = 6(x + 2) Distributive Property x^2 + 2x = 6x + 12 This is quadratic so set it equal to 0. x^2 + 2x - 6x - 12 = 0 or x^2 - 4x - 12 = 0 Then factor (x - 6) (x + 2) = 0 Set each factor equal to 0 and solve x - 6 = 0 so x = 6, x + 2 = 0 so x = -2 6 + -2 = 4
