Answer:
So these two equation can be related by identity 
Step-by-step explanation:
We have given equation 
And 
We know the algebraic identity 
From this identity
can be written as (x+1) (x-1)
And using same identity
can be written as 
So these two equation can be related by identity 
So we want to know what a full box is. We have the weight of half a box. So we can use the formula: (2 x 3/5) and you want to know the outcome of four full boxes. So (2x3/5)4
Or: 6/5 x 4
And the answer is 24/5. But if you want to simplify it, it’s 4 4/5
21/9 + 74/9 = (21 + 74)/9 = 95/9 = 10 5/9
