The guy who links files is pretty annoying amiright...
Divide 18/35 by 3/5 to get your answer. You can also multiply 3/5 by 35/18.
5 goes into 35 7 times, so cross out the 5 and 35 and put 1 and 7. 3 goes into 18 6 times, so cross out the 3 and 18 and put 1 and 6.
Now you have 1/1 times 7/6. Your answer is 7/6.
no it isn't. 2cos(x) is 2 multiplied by cos(x), cos (2x) is cos(2 multiplied by x) meaning 2x is the angle you're taking the cosine of. if you want to know what cos(2x) look up the double angle rule.
Root are also known as what x is equal to. So, to find x you would need to set (x-4)=0 and (x+7)=0
X=4. X=-7
When adding fractions with even denominators, you will not get a whole number, there will be a 1/2. When adding fractions with odd denominators there will be a whole number.
