Answer:
All real numbers
Step-by-step explanation:
2(x + 1) = 2x + 2
2x + 2 = 2x + 2
2x + 2 - 2x - 2 = 2x + 2 - 2x - 2
0 = 0

Answer:
2x -16
Step-by-step explanation:
The area of each rectangle is the product of its length and width. The shaded area is the difference between the areas of the outside rectangle and the inside rectangle.
shaded area = (2x -1)(x +6) -(2x +5)(x +2)
= (2x^2 +11x -6) -(2x^2 +9x +10)
= (2 -2)x^2 +(11 -9)x +(-6 -10)
= 2x -16 . . . . . area of the shaded region
