deff fn [24]3 years ago

Answer:

12, 14, and 16

Step-by-step explanation:

Assume

1st number: x

2nd number: x+2

3rd number: x+4

(I'm adding 2 for each number because even numbers skip by 2)

The numbers add to 42, so

x+(x+2)+(x+4)=42

x+x+2+x+4=42

3x+6=42

3x=36

x=12

1st number: 12

2nd number: 12+2=14

3rd number: 12+4=16

12, 14, and 16

Zolol [24]

Answer:

Well by looking at the products,it must be sodium bicarbonate (NaHCO3)
