Please help I'm almost done the test and need this and one other question ​
PolarNik [594]

Answer:

z=68

Step-by-step explanation:

Use the formula 180\times(n-2) to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (180\times(5-2)=540).

So, we can setup an equation:

70+2z+11+119+z+2z=540

Solve for z:

200+5z=540 Combine like terms

5z=340 Subtract 200

z=68 Divide by 5

Therefore, the value of z = 68.

F (x) = |x + 3| -1 . Find the average rate of change from x = -6 to x = 8
Elenna [48]
Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((<span>|8 + 3| -1) - (</span><span>|-6 + 3| -1))/(8 + 6) = ((</span><span>|11| -1) - (</span><span>|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7</span>
