Question

Another difficult question!! (x+6)/10 divided by (36-x^2)/5

Answer 1

a/b divided by c/d= a/b times d/c

Answer 2

I did set up the reciprocal so I am multiplying but that is where I get stuck!

Answer 3

so you have [(x+6)*5]/[10*(36-x^2)] correct?

Answer 4

Yes

Answer 5

10=2*5 so a 5 can cancel?

Answer 6

so (36-x^2) is equal to (6-x)(6+x)

Answer 7

Ok

Answer 8

since you have 6+x on top and 6+x on bottom that cancels

Answer 9

right

Answer 10

so you 1/[2*(6-x)]

Answer 11

I cancelled the 6+x and now have 5/10(6-x)

Answer 12

but what did we say about that 10

Answer 13

Oh yeah, missed that!!

Answer 14

ok cool!

Answer 15

so then shall I multiply the 2(6-x) and get 12-2x

Answer 16

if you want. When you take calculus though it will be better to leave it as the first way, but if your teacher wants you to mutliply the bottom thats correct

Answer 17

Ok, I am not really sure how he wants it, I am taking an online math class and it sucks!!

Answer 18

the test multiple choice?

Answer 19

Answer 20
