The Least Common Multiple for 3,4,5, and 6 is 60. If you take 60 and divide it by 3 you get 20 If you divide 60 by 4 you get 15. If you take 60 and divide it by 5 you get 12. And if you divide 60 by 6 you get 10. Hope this helps. :)
0.025 ÷ 0.5 = 0.05
lol very quick answer but yea
answer: 0.05
Factoring by grouping usually pairs up the first 2 sets of expressions with the second 2 sets. Ours looks like this, then:
. If we factor out the common x-squared in the first set of parenthesis, along with factoring out the common 5 in the second set, we get this:
. Now the common expression that can be factored out is the (x-9). When we do that, here's what it looks like:
. I'm not sure how far you are going with this. You could set each of those equal to 0 and solve for x in each case. The first one is easy. If x - 9 = 0, then x = 9. The second one involves the imaginary i since x^2 = -5. In that case,
. Hopefully, in what I have given you, you can find what you're looking for.
