19.995
Step-by-step explanation:
Answer would be the bottom answer
Use the remainder theorem: we can decompose the given polynomial in terms of quotient and remainder polynomials
and
, respectively, such that

Then letting x = -3 makes the quotient term vanish, and we're left with a remainder of

I think you would do 15 divided by 5 but I’m not 100% shure
2 t + 2 (1 - 3 t)
= 2t + 2 - 6t (distributive property)
= 2 - 4t (combine like terms)
