For number 4,
You need to convert the decimal to a percentage. To do this, you would move the decimal over 2 spaces to the right. So it would then become 32.5%. If you were trying to convert a percent to a decimal, you would move the decimal over 2 spaces to the left.
Answer:
8-6 is two, so you have 7-y= 2
Y=5 because 7-5=2
Completing the square goes back to pythagorean thm
but the way u do it, u want to find a value that enable u to take sqrt of both sides and solve
x^2-8x+3=0
x^2-8x=-3
we need (x-4)^2 so add 16
(x-4)^2=-3+16
(x-4)^2=13
x-4=sqrt13
x=4(+/-)sqrt13
