Answer:
60
Step-by-step explanation:
The ratio of sizes is ...
blood cell / bacteria = 9×10^-6/(1.5×10^-7) = 90×10^-7/(1.5×10^-7)
= 90/1.5 = 60
The red blood cell's length is 60 times that of the bacteria.
B
5x² - 3 - (x² - 4x - 8)
5x² - 3 - x² + 4x + 8
4x² + 4x + 5
the least common multiple of 8 and 6 is 24
divide
you woukd divide because iches are smaller then meters
-2
