Answer:
A. 15,840 feet
Step-by-step explanation:
1 mile = 5,280 feet (I think "five tomatoes" is helpful: five tomatoes --> five-two-eight-oh)
multiply both sides of equation by 3: 1 * 3 = 5,280 * 3
simplify: 3 miles = 15,840 feet, which means A is the answer
Answer:$9
No
Given 3 sides of a triangle, the sum of any 2 sides must be greater than the third side.
Consider the 3 given sides 1, 7 and 11
7 + 11 = 18 > 1
1 + 11 = 12 > 7
1 + 7 < 11 ⇒ not valid
Hence these sides do not form a triangle
