8. In Math 20-1 class, the teacher gives the class the following rational expressions. 7x-42x x-x-30 x-2x-35 x-49 a. State all non-permissible values of x in the expressions above. (1 mark) b. Determine the simplified product of the two expressions above. (I mark) C The Math 20-1 teacher also gives the class a diagram of a rectangle with dimensions represented by rational expressions, where x>2, as shown below. Explain why x> 2 for the rectangle.
