Analyze the solution shown. 1. –|–x| = 7: given 2. |–x| = –7: multiplication property of equality 3. –x = 7 or –x = –7: definition of absolute value 4. X = –7 or x = 7: multiplication property of equality 5. Check: –|–(–7)| = 7, –7 ≠ 7 –|–7| = 7, 7 = 7 Negative times negative is positive. Determine the flaws in the solution.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
