Question

$$(5x+5)+(2x+7)$$

Evaluate

$7x+12$

Differentiate w.r.t. x

$7$

Steps Using Derivative Rule for Sum

Combine $5x$ and $2x$ to get $7x$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(7x+5+7)$$

Add $5$ and $7$ to get $12$.

$$\frac{\mathrm{d}}{\mathrm{d}x}(7x+12)$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is $0$. The derivative of $ax^{n}$ is $nax^{n-1}$.

$$7x^{1-1}$$

Subtract $1$ from $1$.

$$7x^{0}$$

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

$$7\times 1$$

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

$$7$$
