Answer:
A. The Fabric
Step-by-step explanation:
By definition and experimental unit is the entity which is subjected to different types of treatments during the experiment.
Here the fabric has been stained with different types of stains and and then have been treated with baking soda and bleach under different temperature environments. In the experiment each time the fabric has been given different treatment than the previous one. That's why the fabric is experimental unit in the experiment mentioned in the question.
Step-by-step explanation:
The easiest thing to do here is:
4x + 2 = -2 and 4x + 2 = 26
Just know whaever you get for x is greater or less than the actual answer.
4x + 2 = -2
- 2 - 2
4x = -4

x = -1 <--- Because -2 is supposed to be greater than x, x equals any number less than -1 but not -1.
4x + 2 = 26
- 2 - 2
4x = 24

x = 6 <--- Because 26 is supposed to be less than x, x equals any numbey greater than 6 but not 6
Answer: 31536000X
Step-by-step explanation:
For one year: 365×24×60×60=31536000 seconds.
For x years will be: X×365×24×60×60=31536000X seconds.
Volume of a sphere = (4/3) × π × r3 therefore the answer is 36 pie
