Use a number line if you need 4/10 - 6/10 = -2/10a simpler way is to do the opposite 6/10 - 4/10 = 2/10 then the answer would be the opposite as well. so, -2/10

It's going to become a negative number. You have to change the subtraction sign to addition, then take the second term and change it to a negative. Then you add it. Since one is positive and the other is negative, you have to subtract the absolute values ( just the number without the negative sign) which ever Nemertea has the greater absolute value, that sign is going to be the sign for the answer. I know it's long and confusing. Sorry

6 because the 36 is r² where r is the radius, r² = 36; we have to isolate the r so it's by its self, so square root both sides, r = 6
