A) 8.8 × 10^15 kilograms is the right answer

Step-by-step explanation:

Given

Mass of Phobos = 10.8 * 10^{15}\ kg

Mass of Deimos = 2.0 * 10^{15}\ kg

In order to find how greater is the mass of Phobos from Deimos, the smaller mass will be subtracted from the larger mass

So,

= 10.8*10^{15} - (2.0*10^{15})

As the exponents are same, the numbers can be subtracted directly

=(10.8-2.0) * 10^{15}\\= 8.8*10^{15}\ kg

Hence,

A) 8.8 × 10^15 kilograms is the right answer

X^3 + 2x^2 – 24x<br><br> ^ <br> write the polynomial in factored form
BigorU [14]

Answer:

x(x+6)(x-4)

Step-by-step explanation:

They all have x in it, which means we can factor out x first.

x(x^2 + 2x -24)

Now we can factor out the inside doing algebra.

Since 6 multiplied by -4 gives us -24 and adding them gives us 2, 6 and -4 works. This means that we can factor out (x+6) and (x-4).

We still have to multiply the x from the beginning, giving us a final equation of

x(x+6)(x-4).
