Ok so if it has roots of -3 and 5 it should be divisible by (x+3) and (x-5) and it is also divisible by 2
Therefore it is divisible by 2(x+3)(x-5)
If you multiply that out you get 2x^2 -2x -15
Answer:
5000 particles of size 10 nanometer should be stacked
Step-by-step explanation:
Average diameter of the of the human hair = 50 micron = 50 × 10⁻⁶ m
Now,
let the number of 10 nanometer i.e 10 × 10⁻⁹ m particle be 'n'
thus,
n × 10 × 10⁻⁹ m = 50 × 10⁻⁶ m
Therefore to find the number of 10 nanometer i.e 10 × 10⁻⁹ m particle,
n = 
or
n = 5000
Hence,
5000 particles of size 10 nanometer should be stacked
Inches per second is a convenient unit for ant speed.
Second choice.
