Explain why it works to break apart a number by place values to multiply

Ahyperbola centered at the origin has a vertex at (-6,0) and a focus at (10,0)

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
