Answer:
[tex]-0.6t^2-8+18t[/tex]
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:
[tex](1.3t^3+0.4t^2-24t)-(0.6t^2+8-18t)[/tex]
The additive inverse is:
[tex]-0.6t^2-8+18t[/tex] which is the same expression as [tex](0.6t^2+8-18t)[/tex] but with different signs.
Thus, the additive inverse of the polynomial being subtracted is:
[tex]-0.6t^2-8+18t[/tex]
Answer: -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.
