Show how you can use communitive property to simplify the evaluation of the expression -7/16 -1/4 -5/16.

Since you can directly sum two fractions with the same denominator, we can rearrange the sum as follows:

Now we can sum the first two fraction easily:

We can simplify the first fraction: 12/16=3/4. So, we can sum the two fractions again because they have the same denominator:

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
