Answer:25
Step-by-step explanation:
If you add the 20+5
S = (n-2) x 180 to find the total angles.
5-2*180
3*180
540
540-86-140-138-59=117
round to the nearest
hundredth of milligram : 4.27
tenth of milligram: 4.3
milligram : 4
Treat this as you would the quadratic equation x^2 - 4x - 3 + 0. Solve this by completing the square:
x^2 - 4x + 4 - 4 - 7 = 0
(x^2 - 4x + 4) = 11
(x-2)^2 = 11, and so x-2 = plus or minus sqrt(11).
Graph this, using a dashed curve (not a solid curve). Then shade the coordinate plane ABOVE the graph.
