Step-by-step explanation:
A -box 1
B -box 2
B)- blue ball drawn
18
9*2
You just basically do 9 doubled which is 18
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
