Answer:the length of the third side is 4√7
Step-by-step explanation:
The perimeter of a triangle is 16 to the square root of 7 feet. This is expressed as
Perimeter = 16√7 feet
The perimeter of a triangle is the sum of the length of the three sides of the triangle.
If the two sides measure the square root of 343 feet and the square root of 175, which are expressed as √343 and √175, the third length would be
16√7 - (√343 + √175)
Expressing √343 as a radical, it becomes 7√7
Expressing √175 as a radical, it becomes 5√7
7√7 + 5√7 = 12√7
Therefore, the third length would be
16√7 - 12√7 = 4√7 feet

Answer:
.2
Step-by-step explanation:
Add all the possible outcomes which is 32, then seperate the number of times 5 WILL appear which is 9. Divide 9 by 32 which equals 28% and turn that into a decimal. The answer is .2 hope this helps!!
Step-by-step explanation:
you're going to have to set up two expressions since it's an absolute value problem
Answer and Step-by-step explanation:
Dog meets the train in = 4 minutes
Train catches up the dog in = 12 minutes
Let x be the time when train leave the route,
Train catch up the dog in 12 minutes, the endpoint of route is x and the dog meet up the train in 4min, so the equation becomes:
12 - x = 4
To find out the value of x, subtract 12 from both sides, we get
x = 4 – 12
-x = -8
Which gives x = 8, when train leaves the endpoint of route.
