A rectangle measures 9 inches by 14 inches. If the length and the width are increased by the same amount, the area is increased by 210 square inches. What is the width (or smaller dimension) of the new rectangle?

14*9 + 210 = 336. so (x+14)(x+9) = 336. bash with quad form and you get x=7. so the smaller dimension is 7+9 = 16. plz go help with the following question: (xyz-1)(2xyz + x + y + z + 2) = 2021(x+y+z-2)
