Answer:
llllllllllllllllllllllllllllllllll
Step-by-step explanation:
-9-(12-3x)=-9-1*(12)-1*(-3)=-9-12+3x=-21+3x=3(x-7)
Okay! To do this, all you have to do is multiply the denominator and numerator by the same number.
Let's take number 1 for example:

Choose a number that you want to multiply them by. I'm going to use the number 3.
4 x 3= 12
10 x 3 =30
So your equivalent fraction would be:

Note: Make sure you multiply the top and bottom by the same number. :)
Let me know if you need any more help with the other two.
Factor 64-x^15 in mathhhhgg
(4-x^5) (16+4x^5 +x^10)
:)
My answer would be 95% correct but I give it to you anyways
