Answer:
24
Step-by-step explanation:
Since the ladder, wall, and ground form a right triangle, you can use this formula:
A squared + B squared = C squared
A = 7 feet
C = 25 feet
B = distance the ladder will reach
49 + B squared = 625
B squared = 625 - 49
B = square root of 576
B = 24 feet
Answer:400. 10^2 x 12/3 = 400.
It will be 6hours and a half an hour I hope this helps
Perimeter= 2l+2w
126= 2l+2w
l=2w
Substitute the value for l
126= 2(2w)+2w
126= 4w+2w
126=6w
21=w
Plug the value for w in to find l
l=2(21)
l=42
Final answer: Length-42 ft, Width-21 ft
x=3 and y=2 because 6+6 = 12 and 2 times 3 is 6 :)
