Step-by-step explanation:
use formula
(-b+√b2-4ac)/2a
a=3, b=2 , c=5
(-2+√4-4×3×5)/2×3
(-2+√-56)/6
(-2+2√-14)/6
(-2 +2√14i)/6

Answer:
15%
Step-by-step explanation:
The cost of 2 adults and 2 children without the discount is
2 adults = 2 (55) = 110
2 children = 2 (45) = 90
Total cost = 110+90 = 200
The original price is 200 and the new price is 170
Percentage discount = (Original price - new price)/ original price * 100%
= (200-170)/200 * 100%
= 30/200 * 100%
= .15 * 100%
= 15%
Answer: 272.9 cm^2
How to:
25 * 8 = 200
9 * 8.1 = 72.9
Add the areas of the two rectangles
200 + 72.9 = 272.9 cm^2
