Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.
Examples:
1 and 2
Sum of squares = 5
√5 is irrational
2 and 3
Sum of squares = 13
√13 is irrational
4 and 5
Sum of squares is 41
√41 is irrational
'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .
a 'Pythagorean triple'.
Examples:
3 and 4
Sum of squares is 25
√25 = 5 is rational yay
5 and 12
Sum of squares is 169
√169 = 13 is rational yay
A. 30% is the correct. .30 is 30%
24 tiles
you take 2 yards and 3 yards and multiple them together getting 6 yards, then convert yards to feet resulting in 18 feet, divide that by 1.5 ft and you get 24 tiles.
Answer:
The slope of AB is -3. The equation is y= -3x + 8. The slope of AC = 1, the slope of AD is 4/5, and AE is 1/3. The line most perpendicular to AB would be AE because 1/3 is the opposite of -3.
