Answer:

B. 12x + 8

Step-by-step explanation:

2x + 5 + 4x - 1 + 2x + 5 + 4x - 1

<em>Combine like terms.</em>

6x + 5 - 1 + 2x + 5 + 4x + 1

8x + 5 - 1 + 5 + 4x - 1

12x + 5 - 1 + 5 - 1

12x + 10 - 1 - 1

12x + 10 - 2

<em>Subtract 2 from 10 to get 8.</em>

12x + 8

The perimeter of the rectangle is 12x + 8, which is B.

SpyIntel [72]

Answer:

1,231 people

Step-by-step explanation:

1,256 people currently subscribe. $0.25 is 5 nickels, and for every nickel the price is raised, 5 people unsubscribe. That's 1 person per cent. 25 people will unsubscribe for every $0.25 the price is raised. 1,256-25 is 1,231, so 1,231 people will continue to subscribe after the price increase.
