PLS HELP I NEED NOW!!!

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

so, converting firstly the mixed fractions to improper fractions and then "adding".

4+4+2x

or

2x+8

step-by-step explanation:

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
