Thus, the value on the both sides are not balanced, therefore, Massa is incorrect.

Step-by-step explanation:
Not with whole numbers, your only options would be
6x4 which would have a perimeter of 20
8x3 p=22
12x2 p=28
24x1 p=50
as for decimals, i don't believe that there would be any but not 100% sure
<u>Answer:</u>
29 years
<u>Step-by-step explanation:</u>
- Given the function
, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover. - Another way of doing this is to change the function to
which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate. - I'll use the 1st function because the question doesn't ask for the rate
From here I'll just use a calculator & get 28.7, or 29 years.
