Answer:
Correct Option is d
Step-by-step explanation:
For completing the square our equation should be in the form of
In the given equation we have:
Correct Option is d
B because there are infinite possibilities
The formula for the number of combinations of choosing "r" objects from a larger set of "n" is
combinations = n! / r! * (n - r)!
we know combinations = 35 and r = 3 so we have to solve for "n"
35 = n! / 3! * (n -3)!
n = 7 colors were available
Answer:
Step-by-step explanation:
<u>AB is the diameter, therefore ACB is right angle</u>
- 2x + 5° = 90°
- 2x = 85°
- x = 42.5°
Correct option is A
Robert is incorrect: Surface are of A is 30 + 30 + 42 + 42 + 35 + 35 = 214 square centimeters. Surface area of B is 120 + 120 + 168 + 168 + 140 + 140 = 856 square centimeters. B's surface area is 4 times as great as A's.
