holly is deriving the equation of a line by using one triangle with vertices(0,0), (1,0), and (1,5) and another similar triangle with vertices (-3,-15), (-5,-15), and (-5,-25). Which of these proportions can she set up to help derive the equation?

Adriveway is 60-feet long by 6-feet wide. the length and width of the driveway will each be increased by the same number of feet. the following expression represents the perimeter of the larger driveway: (x + 60) + (x + 6) + (x + 60) + (x + 6) which expression is equivalent to the expression for the perimeter of the larger driveway? a) 2(x + 66) b) 4x + 33 c) 4(x + 33) d) 4(x + 132)
