Step-by-step explanation:

subtract 3 from 7 to get 4

18 x 4 = 18 x 7 + 18 (-3)

multiply 18 and 4 to get 72

72= 18 x 7 + 18 (-3)

multiply 18 and 7 to get 126

multiply 18 and -3 to get -54

72 = 126 - 54

subtract 54 from 126 to get 72

72 = 72

Answer:

A weight hangs from a spring attached to a ceiling, and the weight moves up and down. The table shows the distance in centimeter

sasho [114]

It seemed like it should have been so simple. There was nothing inherently difficult with getting the project done. It was simple and straightforward enough that even a child should have been able to complete it on time, but that wasn't the case. The deadline had arrived and the project remained unfinished.
