Answer: Approximately 96 square feet
======================================================
Work Shown:
1 ft = 30 cm
1 ft = (5*6) cm
1 ft = 5*(6 cm)
1 ft = 5*(1 board width)
1 ft = 5 board widths
12*(1 ft) = 12*(5 board widths)
12 ft = 60 board widths
12 ft = 1 full wall length
The wall is 12 feet horizontally across and 8 feet tall, so its estimated area is 12*8 = 96 square feet approximately. This is approximate because of the fact we used the approximation of 1 ft = 30 cm.
Answer:
∠3=95°
∠4=85°
Step-by-step explanation:
Answer:
(-4 , 0] ∪ (2, ∞)
Last option
Step-by-step explanation:
Since range is included 2 so (2, ∞) and other line is not included 0 but included -4 so it should be (-4, 0]
So range would be:
(-4 , 0] ∪ (2, ∞)
Answer:
Infinitely many solutions.
Step-by-step explanation:
3x-3y=6
-6x+6y=-12
------------------
2(3x-3y)=2(6)
-6x+6y=-12
-------------------
6x-6y=12
-6x+6y=-12
