--------------------------------------------------------------------------------- Define length and width --------------------------------------------------------------------------------- Let the width be x Width = x Length = 3x
--------------------------------------------------------------------------------- Form equation and solve for x --------------------------------------------------------------------------------- x(3x) = 48 3x² = 48 x² = 48 ÷ 3 x² = 16 x = √16 x = 4
--------------------------------------------------------------------------------- Find length and width --------------------------------------------------------------------------------- Width = x = 4 Length = 3x = 3(4) = 12
if the slope of the first problem is -2/7 then its perpendicular is 7/2 (the exact opposite) and since the y- intercept is the b in Y= mx +b the intercept of the equation you’re trying to find is -2
