The area of a rectangle is given by the product of its dimensions.

If this rectangle has a length of 2x + 7 and a width of x + 4, its area is:

$\begin{gathered} \text{Area}=\text{length}\cdot\text{width} \\ \text{Area}=(2x+7)(x+4)_{} \\ \text{Area}=2x^2+8x+7x+28 \\ \text{Area}=2x^2+15x+28 \end{gathered}$

The perimeter is the sum of all side lengths, so we have:

$\begin{gathered} \text{Perimeter}=(2x+7)+(x+4)+(2x+7)+(x+4) \\ \text{Perimeter}=6x+22 \end{gathered}$

Solve the sinusoidal equation:<br><br><br> 5sin(3x)-1=3

adoni [48]

Answer:

$x=0.3090984+\frac{2\pi n}{3},0.73809914+\frac{2\pi n}{3}$

Step-by-step explanation:

$5sin(3x)-1=3$

$5sin(3x)=4$

$sin(3x)=\frac{4}{5}$

$3x=0.92729521+2\pi n,2.21429743+2\pi n$

$x=0.3090984+\frac{2\pi n}{3},0.73809914+\frac{2\pi n}{3}$
