Answer:
x^2-16x+64
Step-by-step explanation:
Simplify= (x-8)(x-8)
Simplified= x^2-8x-8x+64
Combine like terms= x^2-16x+64
Basically whenever the sign is squared on the outside it's the equation times itself. Hope this helps.

Difference = 62.5 micrometer
Step-by-step explanation:
Given that:
Diameter of red blood cell = 7.5 micrometer
Diameter of coarse grain of sand = 70 micrometers
For calculating the difference between two diameters, we will subtract the diameter of red blood cell from diameter of grain of sand.
Difference = 70 - 7.5
Difference = 62.5 micrometer
Hence,
Difference = 62.5 micrometer
