(5x^3 + 3x^2 + 5x) + (7x^3 -3x^2 +8x) = (12x^3 + 13x)
(3x^3 + 5x^2 + 4x) + (9x^3 - 5x^2 + 9x) = (12x^3 + 13x)
30y-27 I believe, but there's no options
Answer:
Area = 18 cm^2
Step-by-step explanation:
1. We can do 360°/80°=4.5
2. To find area of total circle we can do π*(radius)^2= π*(9)^2=81 π
3. Since the shaded region is 4.5 of the whole circle we can do 81/4.5 to find the area of the shaded region.
4. Area = 18 cm^2
Unfortunately, we are not presented in this item with the table in which we could have chosen from our answer to this question. However, it can be concluded that the table which contains the values of
d = p - 2.5
