Suppose that the functions s and t are defined for all real numbers x as follows. S(x) = 6x t(x) =2x+2 Write the expressions for (s+t)(x) and (s-t)(2) and evaluate (s×t)(x)

Answer:

Below in bold.

Step-by-step explanation:

(s + t)x = s(x) + t(x) =  6x + 2x + 2

= 8x + 2.

(s - t)x = s(x) - t(x) =  6x - (2x + 2)

=  4x - 2.

(s x t) = s(x) * (t(x) =  6x(2x + 2)

= 12x^2 + 12x.
