Leg one: x (shorter side)
Leg two: x+6
Hypotenuse: 2x-6
Use a^2+b^2=c^2
x^2+(x+6)^2=(2x-6)^2
x^2+x^2+12x+36=4x^2-24x+36
2x^2+12x=4x^2-24x
36x=2x^2
36 = 2x
x = 18
180/480 =0.375
0.375 = 37.5%
so 37.5% of kids are in 9th grade
Graph K. This is because the cost of a gallon of milk is not increasing constantly, as in a linear rate, but it has only increased a few times in a year. Therefore, graph K shows that a gallon of milk is a steady, unchanged price, then the cost rises and stays the same, then rises again and stays the same. So, it is not a linear graph because the cost of the milk is not going up at a constant rate.
p=3h + 3u subtract 3u from both sides
p-3u=3h now divide both sides by 3
h = p/3 - u
Answer:Rational
Step-by-step explanation:it's not whole, it's not irrational because it's a fraction, and it's not an integar because it's a fraction
