I will use an example.
0.25
0.25 is a fourth of 1, so 1/4

A couple more examples....
0.5 = 1/2
1/3 = 0.3 repeated (the 3 would have a line on top of it)

Derivative Notation

Derivative of a constant is 0

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Step-by-step explanation:

Step 1: Define

$\displaystyle h(s) = (-8s - 9)(-4s + 2)$

Step 2: Differentiate

[Derivative] Product Rule: $\displaystyle h'(s) = \frac{d}{ds}[(-8s - 9)](-4s + 2) + (-8s - 9)\frac{d}{ds}[(-4s + 2)]$
[Derivative] Basic Power Rule: $\displaystyle h'(s) = (1 \cdot -8s^{1 - 1} - 0)(-4s + 2) + (-8s - 9)(1 \cdot -4s^{1 - 1} - 0)$
[Derivative] Simplify: $\displaystyle h'(s) = (-8)(-4s + 2) + (-8s - 9)(-4)$
[Derivative] Distribute [Distributive Property]: $\displaystyle h'(s) = 32s - 16 + 32s + 36$
[Derivative] Combine like terms: $\displaystyle h'(s) = 64s + 20$

Distribute and simplify the expression 3(x + 4) + 2(5 - x)

krek1111 [17]

Answer:

=x+22

-by-step explanation:

Let's simplify step-by-step.

3(x+4)+2(5−x)

Distribute:

=(3)(x)+(3)(4)+(2)(5)+(2)(−x)

=3x+12+10+−2x

Combine Like Terms:

=3x+12+10+−2x

=(3x+−2x)+(12+10)

=x+22
