Jimmy and Tony observed two points, P and Q, on a number line. A number line is shown from negative 1 to positive 1 with increments of 1 over 8. The numbers negative 1, negative 6 over 8, negative 4 over 8, negative 2 over 8, 0, 2 over 8, 4 over 8, 6 over 8 are labeled on the number line. A point P is shown at the fifth tick mark to the left of 0, and a point Q is shown at the fifth place to the right of 0. Jimmy said that the absolute values of the numbers represented by the two points are the same. Tony said that the absolute values of the numbers represented by the two points are different. Which of the following explains who is correct?

pls help soon:)A civil engineer is designing a public parking lot for the new town hall. The number of cars in each row should be six less than the number of rows in the lot. The mayor has requested that the new lot should hold twice as many cars as the current parking lot, which has space for 56 cars.Determine which equation the civil engineer can use to find the number of rows, x, he should include in the new parking lot.A. 2x2 - 12x = 112B. 6x2 - 56 = 112C. x2 - 6x = 112D. x2 - 6 = 112
