Answer: 136 units squared
Explanation: 5*7=35, 5*7=35, 6*7=42, 1/2 of 4*24=12, 1/2 of 4*24=12
35+35+42+12+12= 136 units squared

<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>
To distribute the 2.
2(z-12)-1=z-25+z
First distribute the 2.
2z-24-1=z-25+z
Combine like terms on both sides.
2z-25=2z-25
The two equations have ended up the same. They have an infinite number of solutions.
