Chris is checking to determine if the expressions 2(x+3) and 2 x+4+2x are equivalent. when x=1 , he correctly finds both expressions have a value of 8. when x=2, he correctly evaluates the first expression to find that 2(x+3)=10

These expressions are not equivalent

Step-by-step explanation:

You could simplify/rewrite them and see that 2x+6 ≠ 4x+4

There will be a point where they are equal but the expressions themselves are not equal for all real numbers

when x = 2, 2x +4 +2x =12

2(x+3) is not equal to 2x + 4 + 2x

Step-by-step explanation:

when x = 1

2(1+3) = 2(1) + 4 +2(1)

8 = 8

The equation are equivalent at this this point

at x= 2

2(2+3) = 2(2) + 4 + 2(2)

10 \= 12

10 is not equal to 12

at x=1 , the equations are equal, but the equations are not equals in any points.

1.true 2.false? ? i think. .
