Write a linear expression in simplest form to represent the perimeter of the triangle at the right. Then find the
perimeter if the value of x is 10 millimeters.

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.

What are the solutions of the equation x4 – 5x2 – 14 = 0? use factoring to solve. someone !

How would you describe the difference between the graphs of f(x) = 2x2 and g(x) = -2x2?
