What is the value of x?​

Mathematics
1 answer:
Gwar [14]2 years ago
3 0

Answer:

Step-by-step explanation:

First count the number of sides. There are 6 sides.

Now use the formula

(n - 2) * 180  To determine the total of all 6 angles.

(6 -2) * 180 =

4 * 180 = 720

Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.

x + 4 + 120 + x + 50 + 140 + 112 + x = 720     Combine

3x + 4 + 120 + 50 + 140 + 112 = 720

3x + 426 = 720                                                Subtract 431 from both sides

3x = 720 - 426                                                 Combine

3x = 294                                                          Divide by 3

x = 294/3

x = 98

F(x)=-2x+1; {-2,0,2,4,6} Find the range of the function for the given domain.
3241004551 [841]

Answer:

For the domain indicated, the range is  {-11, -7, -3, 1, 5}

Step-by-step explanation:

Given the indicated domain of f(x) you have to replace the values in the function to find the range (the "y" values of the function).

f(-2) = 5

f(0) = 1

f(2) = -3

f(4) = -7

f(6) = -11.

So the range for this domain is {-11, -7, -3, 1, 5}
