Help me with part c? I already did A and B.
Question: The area of rectangle A can be expressed by the polynomial 8x^2 + 2x  3. The area of rectangle B can be expressed by the polynomial 32x^2 + 8x  12.
Part A: Factor the expression for the area of rectangle A.
Part B: Factor the expression for the area of rectangle B.
Part C: Every dimension of rectangle A was multiplied by a scale factor to get
rectangle B. What was the scale factor? Explain how you know.
Part A: (2x  1) (4x + 3)
Part B: (8x  4) (4x + 3)
Part C: ?

Best ResponseYou've already chosen the best response.0For rectA, you have (2x  1)(4x + 3). For rectB, you have (8x  4)(4x + 3). Both areas have a common factor of (at least) (4x + 3). You can still factor the expression for rectB.
