Answer:
The length of each side of the base is 
Step-by-step explanation:
we know that
The area of a square is equal to
where
b is the length side of a square
In this problem we have
so
substitute in the formula
Square root both sides
Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages
The system of equation which represent the scenario is;
x + y = 42
x + y = 420.13x + 0.18y = 6.66
<h3>Simultaneous equation</h3>
let
- number of 13 cent stamps = x
- number of 18 cent stamps = y
- Total cost of the stamps = $6.66
- Total number of stamps = 42
x + y = 42
x + y = 420.13x + 0.18y = 6.66
Therefore, the equation which represent the problem is;
x + y = 42
0.13x + 0.18y = 6.66
