Simplify the following expression: 9(2x - 3) + 30

9(2x−3)+3

Distribute:

=(9)(2x)+(9)(−3)+3

=18x+−27+3

Combine Like Terms:

=18x+−27+3

=(18x)+(−27+3)

=18x+−24

alot

step-by-step explanation:

its a wood chuck that can chuck wood

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.
