Answer:
- Deck's width is 6 feet.
- The area is 72 sq. ft.
Step-by-step explanation:
First, label it out:
- Length: 12 ft.
- Width: ?
- Area: ?
Then, we add up 12 twice (Since the length is on 2 sides):
- 12 + 12 = 24
- 36 - 24 = 12
- 12 - ? = ?
Now, we write down a 6 in the ?:
Width = 6.
We are not done!
Now, we have to solve for area.

Answers are:</h2><h2>
Area = 72 sq. ft.</h2><h2>
Width = 6 ft.</h2>
H(-2) = 2(-2)^2 - 3(-2)
= 2(4) - (-6)
= 8 + 6
= 14
The answer is 12 and she might have divided it by 2.
The answer is: C
The lower extreme is 9
The upper extreme is 22
The median is 15
The first quartile is 11
The third quartile is 19

Answer:
Step-by-step explanation:
From the data given,
∠MON=8x−13
∠LOM=7x−17
∠LON= is a straight line angle, i.e. it is 180°
Then, the sum of MON and LOM is equal to LON
∠MON + ∠LOM = ∠LON
8x-13 + 7x - 17 = 180
15x -30 = 180
15x = 180+30
15x =210
x =210/15
x = 14°
We want to find MON
∠MON=8x−13
∠MON=8(14)−13
∠MON=112−13
∠MON= 99°
