PLEASE GEOMETRY HELP WILL MARK BRAINLIEST!!!
labwork [276]

Answer:

3240°

Explanation:

The formula for calculating the sum of the interior angles of a polygon is (n-2)x180 where n refers to the number of sides. Because we know that the polygon has 20 sides, the equation would be (20-2)x180. The answer would be 3240°.

If f(x) = 3^+ 10 and g(x) = 2x - 4, find (f - g)(x).
just olya [345]

Answer:

3^x -2x +14

Step-by-step explanation:

I will assume you mean 3^x in the function f(x)

f(x) = 3^x+ 10

g(x) = 2x - 4

(f - g)(x) =  3^x+ 10  - (2x - 4)

       Distribute the minus sign

              =  3^x+ 10  - 2x + 4

              = 3^x -2x +14

Solve for y: -2(5y-1)-y=-4(y-3)
Talja [164]

Answer:

<h2>y =  -  \frac{10}{7}</h2>

Step-by-step explanation:

- 2(5y - 1) - y = - 4(y - 3)

Expand the terms in the bracket

That's

-10y + 2 - y = - 4y + 12

Group like terms

Send the constants to the right side of the equation and those with variables to the left side

That's

- 10y - y + 4y = 12 - 2

- 7y = 10

Divide both sides by - 7

We have the final answer as

<h3>y =  -  \frac{10}{7}</h3>

Hope this helps you
