Can someone help me with this ONE question? Write an equation.. and solve for X
matrenka [14]

Answer:

Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

x=17

Step-by-step explanation:

A 6 sided polygon is 720° degrees

so

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

flip equation:

26x+278=720

subtract 278 from both sides

26x=442

divide by 26 both sides:

x=17

Hope this helps.

Evaluate the indefinite integral. (Use C for the constant of integration.) <br> ex 5 ex dx.
melisa1 [442]

Answer:

  5 e^{x} +C

where C is constant of integration

Step-by-step explanation:

<u><em>Explanation:-</em></u>

<em>Given f(x) = 5 eˣ</em>

Now integrating with respective to 'x' , we get

                                                      I =  \int\limits {5 e^{x} } \, d x

<em> By using integration formula</em>

                                       \int\limits { e^{x} } \, d x = e^{x} +C

                                     I =  \int\limits {5 e^{x} } \, d x  = 5 e^{x} +C

<em>where C is constant of integration</em>

Does anyone know this?
vladimir2022 [97]

Answer:

x = 4

Step-by-step explanation:

By BPT

\frac{10 - x}{x}  =  \frac{3}{2}  \\  \\ 2(10 - x) = 3x \\  \\ 20 - 2x = 3x \\  \\ 20 = 2x + 3x \\  \\ 20 = 5x \\  \\ x =  \frac{20}{5}  \\  \\ x = 4
