The **number** in each of the set of blank boxes is 10

<h3>How to find the number set equivalent?</h3>

From the first **number set** of stamps, we see that the sum of each row is;

5 + 5 + 5 + 5 = 20

There are four rows. Thus;

**Total sum** of set of stamps = 20 + 20 + 20 + 20

**Total sum** of set of stamps = 80

Now, for the **blank set **of stamps, we see that there are 8 boxes which are al equal. Now, for this 8 boxes t have same sum as that of the initial set of stamps, it means they must sum up to 80.

If the number in each box is x, then;

8x = 80

x = 80/8

x = 10

Thus, the number in each of the set of blank boxes is 10

**Answer:**

**x-2**

**Step-by-step explanation:**

The formula for area of rectangle is **length x width**

And we know that width is** x-16**

And we know that the area is** **

So we know that when x-2 is multiplied with x-16, it gives off
