(C) Given $f(x) = (kx + e^x) h(x)$.Using the product rule for differentiation,$f'(x) = \frac{d}{dx}(kx + e^x) \cdot h(x) + (kx + e^x) \cdot h'(x)$.$f'(x) = (k + e^x) h(x) + (kx + e^x) h'(x)$.Now,substitute $x = 0$ into the expression for $f'(x)$:$f'(0) = (k + e^0) h(0) + (k(0) + e^0) h'(0)$.$f'(0) = (k + 1) h(0) + (1) h'(0)$.Given $f'(0) = 18$,$h(0) = 5$,and $h'(0) = -2$:$18 = (k + 1)(5) + (-2)$.$18 = 5k + 5 - 2$.$18 = 5k + 3$.$15 = 5k$.$k = 3$.

Let $h(x)$ be differentiable for all $x$ and let $f(x) = (kx + e^x) h(x)$. Where $k$ is some constant. If $h(0) = 5$,$h'(0) = -2$,and $f'(0) = 18$,then the value of $k$ is equal to:
