You need to add 12.

You need to add 7 (or +7)

7/6 or 1 1/6 If you want to add 2/3 and 1/2 you first need to find a common denominator. In this case, 6 is the least common denominator. Then you rewrite the fractions with the new denominator. 2/3=4/6 and 1/2=3/6. Now you can add them. 4/6+3/6=7/6 and 7/6 is the same as 1 and 1/6.

A=x^2+10x+24 you need two numbers that will multiply to 24 and add to 10 (x+4) (x+6) 4 and 6 add up to 10 and multiply to equal 24 A = n^2+n-2 you need two numbers that will add up to one and multiply to -2 (n+2)(n-1) 2 and -1 add up to 1 and multiply to equal -2

Least common denominators or LCDs are very important when adding fractions.For example, if we want to add 1/2 and 1/3 we need to make them look the same. That is to say we can only add like things. So we find the LCD which is 6 in this case. 1/2 is 3/6 and 1/3 is 2/6. Now we can add these and we have 5/6.Without the LCD we could not add these or many other fractions.We extend this idea when we add rational expressions.

You need to add 6 - (-9) = 6 + 9 = 15.

They need a common denominator when you add them. For example, if you want to add 1/2 and 1/3, you need to change the fractions to equivalents that share the same denominator, so you can combine them. 1/2 + 1/3 = 3/6 + 2/6 = 5/6

2+2+2=6 6/2=3

Fractions will need to have the same denominator to add the numerator then reduce the answer as needed to simplest forms. 1/2 + 1/3=3/6 + 2/6=5/6
