If y varies directly as the square of x, that means that y=k*x^2. Plugging y=100 and x=5 into it, we get 100=k*5^2=k*25. Dividing by both sides, we get k=100/25=4. Going back to the original equation, we now know that y=4*x^2. Plugging 9=x in, we get 4*9^2=4*81=324=y
= 7.348469228
this is irrational, because it cannot be written in the form

Answer:
Hello :D
Step-by-step explanation:
1/3=2/6
-1/6= -1/6
then I guessing you add them?
2/6+-1/6=1/6
Answer:
4x+5x=90
9x=90
x=90/9
x=10
4x=40
5x=50
hence the angles are 40 degree and 50 degree respectively.
Hope this may help you
Thank you
