The length of a rectangular frame is represented by the expression 3x + 10, and the width of the rectangular frame is represented by the expression 3x + 6. Write an equation to solve for the width of a rectangular frame that has a total area of 192 square inches.
a
9x2 + 48x + 60 = 0
b
9x2 + 48x − 132 = 0
c
3x2 + 48x − 132 = 0
d
x2 + 16x + 60 = 0
