There are two ways you can find the answer to this question and both ways will give you the correct answer.

Method One:

If 240 bolts are produce in 25 minutes
then the number of bolts produced per minute  =  240bolts ÷  25min
                                                                           =  9.6 bolts/ min

∴ bolts produced in 45 minutes   =   9.6 bolts/min ×  45min
                                                    =   432 bolts


Method TWO

240  bolts  is produced in 25 mins                240 bolts    →    25 mins
   x      bolts are produced in 45 mins                 x           →     45 mins
                                                                   
                                                                           25x  =  (240)(45)
                                                                               x  =  10800 ÷ 25
                                                                                   =  432

Solve for 2x^2-4x+5=6
Softa [21]
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 = \frac{-b \pm  \sqrt{b^2 - 4ac} }{2a}   Plug in your values
x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4(2)(-1)} }{2(2)}   Simplify
x = \frac{4 \pm \sqrt{16 + 8} }{4}   Simplify
x = \frac{4 \pm 2\sqrt{6} }{4}   Simplify by removing a 2 from every term
x = \frac{2 \pm \sqrt{6} }{2}   Simplify by taking the fraction apart
x = \frac{2}{2}  \pm  \frac{ \sqrt{6} }{2}   Change \frac{2}{2} to 1
x = 1 \pm  \frac{ \sqrt{6} }{2}   Simplify \frac{ \sqrt{6} }{2} to \sqrt{ \frac{3}{2} }
x = 1 \pm \sqrt{ \frac{3}{2} }
