Solve 20x + 12 > 14x + 30 A . x>7

B. x>3

C. x<3

D. x<7

B. x>3

Step-by-step explanation:

20x + 12 > 14x + 30 import like terms to the same side of the equation

20x - 14x > 30 - 12

6x > 18 divide both sides by 6

x > 3

20x + 12 > 14x + 30

Get like terms all on the same side

6x > 18

Divide both sides by the number in front of the x

x > 3

Hope this helps! :)

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
