35 + 3n= x 
x being the total amount of stamps!

is there a substitution for n? or a number of months?

Answer:

a_n = 3n + 32

Step-by-step explanation:

Ava purchased a set of 35 stamps. Each month, starting the second month, she purchased 3 more stamps for her collection.

So first month she has 35 stamps, second months she has 38 stamps and so on...

35, 38, 41, 44........

This is arithmetic sequence , so we use formula

a_n = a_1+(n-1)d

Where a1 is the first term and d is the difference

a1= 35, d= 3

so formula becomes

a_n = 35+(n-1)3

a_n = 35+3n - 3

a_n = 3n + 32

Amy is solving the equation using the steps shown.
Delicious77 [7]

The correct next step Amy could take is to factor (x^2 - 16) on the left side of the equation to yield (x + 4)(x – 4)(x + 2) = 0.

The equation is given as:

\mathbf{(x^2 - 16)(x + 2) = 0}

The possible next steps are:

1. Expand the equation as follows

\mathbf{x^3+2x^2-16x-32 = 0}

2. Express x^2 -16 as a difference of two squares as follows

\mathbf{(x + 4)(x- 4)(x + 2) = 0}

However, the correct step in this case is to factor x^2 - 16 as a difference of two squares to give \mathbf{(x + 4)(x- 4)(x + 2) = 0}

This is so, because the question says Amy is trying to solve for variable x.

This step will ensure that she gets the possible values of x, unlike expanding the whole equation .

Hence, the correct next step is \mathbf{(x + 4)(x- 4)(x + 2) = 0}
