Answer:

11 + 16n

Step-by-step explanation:

Collect the like terms

How do you solve for the area for a complex figure
Dmitriy789 [7]

Step-by-step explanation:

It varies depending on the structure of the figure your taling about. If it is a bunch of squares or rectangles, you get the perimeter of all sides and then you try to make the figure into smaller squares or rectangles. After that now find the perimeter of the new side (opposit side should tell you) and then find the area for all the rectangles and squares. After that step, you add all the areas together and...viola!!!! You get the area of the complex figure. If it is not a rectangle please comment with the object and I could help you.

Solve: 2 + = 2. Give solutions in interval [0, 2)
Dovator [93]
\because\cos 2x+\sin x=\sin 2x\because\sin 2x=2\sin xcosx\because\cos 2x=\cos ^2x-\sin ^2x

→ Substitute cos 2x and sin 2x by their expressions

\therefore\cos ^2x-\sin ^2+\sin x=2\sin x\cos x

→ Subtract both sides by sin x

\cos ^2x-\sin ^2x=2\sin xcosx-\sin x

→ Take sin x as a common factor in the right side

\therefore\cos ^2x-\sin ^2x=\sin x(2\cos x-1)

From the graph, the equation has 4 solutions, the intersection points between the 2 graphs

Question<br> Find the distance between the points (-5, 8) and (-3,0).
Temka [501]

To calculate the distance between two points we use this formula:

\boxed{ \boxed{{d \:  =   \:  \sqrt{(x_2 \:  -  \: x_1)^{2} \:  +  \: (y_2 \:  -  \: y_1)^{2} } }}}

<h3>______________________</h3>

<h3>We organize the values:</h3>

  • x₁ = -5
  • x₂ = -3
  • y₁ = 8
  • y₂ = 0

______________________

We apply the values already obtained to the formula to get the distance:

d \:  =   \:  \sqrt{( - 3 \:  -  \:( - 5))^{2} \:  +  \: (0 \:  -  \: 8)^{2} }

d \:  =   \:  \sqrt{( - 3 \:  -  \: ( - 5))^{2} \:  +  \: ( - 8)^{2} }

d \:  =  \:  \sqrt{( - 3 \:  +  \: 5) ^{2}  \:  +  \: 64 }

d \:  =  \:  \sqrt{ {2}^{2} \:  +  \: 64 }

d \:  =  \:  \sqrt{4 \:  +  \: 64}

d \:  =  \:  \sqrt{68}

d \:  = \boxed{ \bold{  \: 2 \sqrt{17}  \:   units}}

<h2>Answer: </h2>

\huge{\boxed{ \bold{2 \sqrt{17} \: units }}}
