Answer:
to find the distance between two points, in order to find the length of the triangle we need first to find the instance between the two points
distance between (2,9) and (2,4) .....a =5
distance between (2,4) and (6,4) .....b = 4
when we find the length of the side of the triangle , then we can apply the Pythagorean theorem to find hyp. c
a²+b²=c²
Answer: 12
Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

Answer:

Step-by-step explanation:
To convert a mixed fraction to a improper fraction, you have to multiply the denominator (2) by the whole number (8). 8 multiplied by 2 is 16. Then add the numerator (1). 16+1=17. That becomes your numerator, the denominator (2) stays the same.

Remember a square is all right angles and the length of all the sides are the same
