The table below shows the proportional relationship between the weight of oatmeal, in ounces, and the number of packs of oatmeal:

number of packs of oatmeal number of ounces of oatmeal
4 44
5 55
7 77

what is the constant of proportionality?

It is A: 11

Step-by-step explanation: It is 11 because if you multiply each of the numbers by eleven for example 4 * 11= 44

we know that

The perfect square trinomial in this problem is equal to

in this problem we have

Let

so

therefore

the answer is

To make the left side a perfect-square trinomial must be added to both sides of the equation the value of
