What should be the first step to solve the equation? 2x + 9(x - 1) = 8(2x + 2) - 5

A. Combine like terms on each side of the equation.

B. Use the distributive property on each side of the equation.

C. Use the subtraction property of equality to subtract 5 from each side of the equation.

D. Use the addition property of equality to add 2x to each side of the equation.

B.

Step-by-step explanation:

You will need to get rid of the parenthesis to make the problem easier for you to work with. Since there is a number in front of the parenthesis, you will need to distribute that to both numbers in the parenthesis.

For this example, you would multiply the 9 to both the x and -1, and then 8 to both 2x and 2.

step-by-step explanation:

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

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
