What is the simplified form of the following expression?

Step-by-step explanation:

To simplify, multiply the coefficients of the terms and add the exponents of the same variable together. So, multiply 2 and -2 together, and add the exponents 7 and 9 together while keeping the variable of x:  

·

Thus, the answer is .

step-by-step explanation:

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

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

only 10/60 isn't equivalent

hope this : )
