Answer:
Step-by-step explanation:
Given
The wavelength of light is 0.0000014 inches
Here, seven digits are followed by a decimal point
To convert it to scientific notation, convert it into a fraction i.e.
In the denominator, there are 7 zeroes
(x^2 +3)(5x+9)
5x^3 + 9x^2 + 15x + 27
1A: 10,000
bc volume= length x width x height and 10x10x10=10,000
1B: 600
area= length x width, then add the area of each of the sides (100)
You are correct but I do not know what the last are sorry
