Answer:
the square root of 64a^2/9b^2+4+32a/3b is
or
Since we will be completing the square we need to isolate the x
y-5 = 2x^2 -4x
now we the coefficient of the x^2 to equal 1 so we take 2 as common factor
y-5 = 2(x^2 -2x)
now we'll make it perfect square by adding 2 to both sides
y-5+2=2(x^2-2x+1)
now simplify and convert the right side to squared expression
y-3 = 2(x-1)^2
now isolate the y
y = 2(x-1)^2 +3 that's it
You have to subtract 3.2 from 3.5 to get x. 0.3+ 3.2=2.5 so x=0.3
Answer:
x=65
Step-by-step explanation:
x-5=60
Add 5 to both sides
x=65
