The dimensions are 6cm and 4cm
May be there is an operator missing in the first function, h(x). I will solve this in two ways, 1) as if the h(x) = 5x and 2) as if h(x) = 5 + x
1) If h(x) = 5x and k(x) = 1/x
Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)
2) If h(x) = 5 + x and k (x) = 1/x
Then (k o h)(x) =k ( h(x) ) = k (5+x) = 1 / [5 + x]
Everything separated by a '+' or '-' sign separates a term so in this expression there are 2 terms
The third option has like terms as they can be added based on the term. For example numbers with x, x^2, x^3 etc can be added together. For example x+x can be added but x+x^2 can’t. They have different terms that make them different.
