Question

$$5x+7x$$

Differentiate w.r.t. x

$12$

Steps Using Definition of a Derivative

Combine $5x$ and $7x$ to get $12x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(12x)$$

The derivative of $ax^{n}$ is $nax^{n-1}$.

$$12x^{1-1}$$

Subtract $1$ from $1$.

$$12x^{0}$$

For any term $t$ except $0$, $t^{0}=1$.

$$12\times 1$$

For any term $t$, $t\times 1=t$ and $1t=t$.

$$12$$
