<h3><u>Answer;</u></h3>
= 3,391 viruses
<h3><u>
Explanation;</u></h3>
- The population density is 1.2 viruses per square millimeter.
- This means, each square millimeter is occupied by a population of 1.2 viruses.
Therefore; for an area of 2,826 square millimeters, there will be;
= 2,826 multiplied by 1.2 viruses
= 2,826 × 1.2
= 3391.2 viruses,
and since we can have a fraction or decimal virus then the population would be <u>3391 viruses</u>
Answer:
16
Step-by-step explanation:
A square has same length on all sides.
So, 18x-20=42-13x
18x+13x=42+20
31x=62
x=62/31=2
Now you can substitute x=2 in one of the equations to find the length of the side.
18x-20 = (18*2)-20 = 36-20 = 16
