Complete the tasks to subtract the polynomials vertically. (1.3t3 + 0.4t2 – 24t) – (0.6t2 + 8 – 18t) what is the additive inverse of the polynomial being subtracted? –0.6t2 + (–8) + (–18t) –0.6t2 + (–8) + 18t –0.6t2 + 8 – 18t 0.6t2 + (–8) + 18t

Step-by-step explanation:

We know that the additive inverse are two equal numbers or expressions but with different signs.

Now, the given polynomials are:

The additive inverse is:

which is the same expression as but with different signs.

Thus, the additive inverse of the polynomial being subtracted is:

-0.6t^2 + (-8) + 18 & the answer for the second part is "B" and the answer for the third part is 1.3t^3 - 0.2t^2 - 6t - 8

Step-by-step explanation: trust me I just did it.
