Answer:

n^2 - 25

Step-by-step explanation:

These dimensions are the difference and the sum of two quantities.

Recall that (a - b)(a + b) = a^2 - b^2 (no middle term).

The area of this rectangle is A = (n - 5)(n + 5) = n^2 - 25

umka21 [38]

Answer:

The cost of each cotton candy bag is $4.

Step-by-step explanation:

Consider the provided information.

Let, the vendor has x dollar at the starting of each day.

Let, the cost of each cotton candy bag is y.

Now when she sells a total of 12 bags, she has $128.

x+12y=128  .....(1)

After she sells a total of 20 bags, she has $160.

x+20y=160  ....(2)

Subtract equation 1 from equation 2.

(x+20y)-(x+12y)=160-128

8y=32

y=4

Hence, the cost of each cotton candy bag is $4.
