Answer:
i dont no sorry about that
To solve for a variable, you need to get it (x) by itself.
2x² - 4x + 5 = 6 Subtract 6 from both sides
2x² - 4x - 1 = 0 Plug this into the Quadratic Formula
a = 2 , b = -4 , c = -1
x =

Plug in your values
x =

Simplify
x =

Simplify
x =

Simplify by removing a 2 from every term
x =

Simplify by taking the fraction apart
x =

Change

to 1
x = 1

Simplify

to
x = 1
14 is .608, roundedto the nearest percent 14 is 61% of 23
1= 15
2= 12
Hope this helps
90 divided by 2= 45 so x=45
2•45=90
So, for the next one y=60 because 90+90=180
3•60-2•45=90
