Timmy wrote the expression 5(x + 2) as 5x+2. Explain whether or not Timmy’s math is correct.

Timmy's expression is wrong

If you do this expression 5(x+2) the results are gonna be 5x+10. If Timmy did the expression like 5x+2, the expression is going to stay like this because that is the result, you can't do anymore after that.

5x+2 ≠ 5(x+2)

No es correcto por que en la primera ecuación 5 afecta a X y a 2 , pero en la segunda 5 solo afecta  x

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
