Step-by-step explanation:
Answer:
1120 grams
Step-by-step explanation:
The amount of sea water is directly proportional to the amount of salt in the water.
Let the amount of sea water be W and the amount of salt be S.
This means that:
W α S
=> W = kS
where k = constant of proportionality
2 liters of sea water contain 70 grams of salt Therefore:
2 = k * 70
k = 2 / 70 = 1/35
Therefore, for 32 liters of sea water:
32 = 1/35 * S
S = 35 * 32
S = 1120 grams
There are 1120 grams of salt in 32 liters of water.

Answer: (ab - c)(ab + c)</h3>
===================================================
Work Shown:
a^2b^2 - c^2
(ab)^2 - c^2
(ab - c)(ab + c)
In the last step, I used the difference of squares factoring rule.
