Determine whether each set of numbers is a phythagorean triple.
5,9,11
8,10,6
i really need someone to me with this, i wasn't at school when the teacher taught it and i dont know how.

-- Find the square of all 3 numbers.

-- if the biggest square is equal to the sum of the other two squares, then the original three numbers are a Pythagorean triple.

If you draw a triangle and use those numbers for the lengths of the sides, then the triangle has a right angle (90 degrees) in it.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
