Answer:

part a. A

part b. x + 6

part c. (4x – 1)(3x + 6)

Step-by-step explanation:

width + x + x = 3x + 6

width = 3x + 6 – x – x /answer for part a/

width = x + 6 /answer for part b/

Area = (length)(width) = (4x – 1)(3x +6) /part c/

Answer:

Part A: A

Part B: x+6

Part C: 12x^2 + 21x - 6

Step-by-step explanation:

Part A:

Width of the door

= (3x+6) -x -x

Part B:

Width of the door

= (3x+6)-x-x

Bringing like terms together,

= 3x-x-x+6

= 3x-2x+6

= (3x-2x)+6

= x+6

Part C:

Area of the rectangular room = Length*Width

= (4x-1)*(3x+6)

= 4x*3x - 1*3x + 6*4x - 6

= 12x^2 - 3x + 24x - 6

= 12x^2 + 21x - 6
