Answer:
17w + 8
Step-by-step explanation:
You would add 6w + 11w because they are like expressions. They you would add 4+4 because they are also like expressions.
The greatest common factor is 5
18 inches=1.5 ft
Since the border extends around the entire circumference, it adds 3 ft to the total diameter of the border and pond.
3.14*3.5^2=38.465
Subtract the area of just the pond from this
3.14*2^2=12.56
38.465-12.56=25.905
Final answer: 25.905 ft^2
Answer:
135
Step-by-step explanation:
Okay so we know that all angles in tringle sums up to 180
Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg
We also know that angles on a straight line add up to 180deg as well
Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg
