The area of an 11-cm-wide rectangle is 242cm2. what is it's length

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7); m=-3/2

Which shows the correct lengths of side c in both scales? scale 1: 45 m; scale 2: 60 m scale 1: 60 m; scale 2: 45 m scale 1: 36 m; scale 2: 27 m scale 1: 27 m; scale 2: 36 m mark this and return save and exit

What is the missing step in this proof ?
