Distributive Property Practice Remember: Multiply BOTH pieces inside the parentheses by the number outside of the parentheses.

4(3x+ 2)

3(7y-1)

5(3p + 4r)

3(2w - 5y)

10(10e + 7g)

8(2b + 5)

7(c + 7)

9(6a +x)

1:  12x + 8                  

2:  21y  - 3

3:  15p + 20r

Step-by-step explanation:

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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.
