Part 2: Identify key features and graph a circle from general form. Answer the following questions to determine the key features of the circle whose equation is shown
and then graph it.
x2 + y2 + 12x – 2y - 12 = 0

a) Write the equation of the circle in standard form. (3 points)

b) What is the center of the circle? (1 point)

c) What is the radius of the circle? (1 points)

d) Sketch a graph of the circle and label the center and the endpoints of the horizontal and vertical
diameter. (4 points)

Which one is true about the hexagons ?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

The sum of the squares of two numbers is 8 . the product of the two numbers is 4. find the numbers.
