Simplify the expression by combing all like terms x +2 + x + 2 + x

4 + 3x

Step-by-step explanation:

2 + 2 = 4

Add the three x's together and you get 3x!

Hope this helps! ^^

3x+4

Step-by-step explanation:

To simplify: x+2+x+2+x you need to combine the like terms, which in this case, would be the x's and 2s.

Add together all of the x's --> 3x

Add together all of the 2's --> 4

Therefore, the answer is: 3x+4

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.
