The mass of a clownfish is 2.5 x 10 to the negative 1 power kilograms. the mass of a pilot whale is 3 x 10 to the third power kilograms. about how many times as massive is the pilot whale than the clownfish?

Mass of pilot whale is 1.2 X 10 ^4 times massive than Mass of clownfish.

Step-by-step explanation:

Mass of clown fish = 2.5 X 10 ^-1 kg

Mass of pilot whale = 3 X 10 ^ 3 kg

Find the ratio of Mass of pilot whale to the ratio of Mass of clown fish

Mass of pilot whale : Mass of clown fish

3 X 10 ^ 3 : 2.5 X 10 ^-1

It can be written as

3 X 10 ^ 3 / 2.5 X 10 ^-1

1.2 x 10^4

So, Mass of pilot whale is 1.2 X 10 ^4 times massive than Mass of clownfish.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

step-by-step explanation:

if x = 2 you have to find x to finish the problem
