First, take half of the coefficient of 18x then square it.
18 / 2 = 9
9^2 = 81
So, D. 81 is the answer.
Answer:
x = 16
Step-by-step explanation:
(5x + 12)° + (6x - 8)° = 180°
(5x + 12 + 6x - 8)° = 180°
(11x + 4)° = 180°
11x + 4 = 180
11x = 180- 4
11x = 176
x = 176/11
x = 16
So what you would do is divide 37 minutes by 5 to get 7.4 minutes
answer: 7.4 minutes
The square footage of the room is length times width...in this case 16 x 12 =192 then divide that by 7 and it can accommodate 27 people.
