You would use the formula P(1+r/n)^nt=A I explained it in the picture and if the number is growing it is 1+r/n and if it’s not it is 1-r/n. Also if you don’t know the formula you can do it year by year which I also showed but it will take a long time and it’s easy to make a mistake. The answer would be A because if you plug the numbers into the formula you will get 4045.56 for plan b then you subtract 3000 and round, getting 1046. It is the formula of exponential growth/decay if you want to research further.

Ksenya-84 [330]

Answer:

10 (X+1)

Step-by-step explanation:

Length = 2x + 5

Width = 3x

Perimeter of rectangle= 2(L + W)

P= $2\times (2x+5+3x)$

P= $2\times (5x+ 5)$

Now, taking 5 as common

P= $2\times 5 (x + 1)$

∴ Perimeter of rectangle= $10\times (x+1)$
