(4x + 7) - (x+1)
A. 3x + 8
B. 3x + 6
C. 4x + 8
O D. 4x + 6

Lmk

4x + 7 - ( x + 1)

Remove the bracket

We get

4x + 7 - x - 1

= 3x + 6

That's option B

Hope this helps.

(4x + 7) - (x+1)

Remove the brackets and distribute the negative sign to x+1.

4x + 7 - x - 1

4x - x + 7 - 1

Add or subtract like terms.

y=mx+b is the final answer!   : )

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.
