Let us determine the product of 438 and 17 by partial products.
Consider 
and 
So, 

= 
= 7446
Therefore, the product of 438 and 17 is 7446.
No, Sandra's answer is not correct.
Because she should have expressed 17 as (10+7), then if she multiplied (438 by 10) and (438 by 7). And, then added the results.Then her answer would be correct.
They both have the same absolute value. Their absolute value would be 3
Answer:
Option C
Step-by-step explanation:
Option D's unit is not used in volume measurement. A "ton" is 2,000 lbs. Pounds are not used to measure volume.
Since we are looking at the volume of a "large tank", then a quart and a pint would be too small, and therefore, not the most appropriate units to measure the volume of the tank with.
A "kiloliter" is equivalent to 1,000 liters. Note that the prefix "Kilo-" means 1,000. A kiloliter would be appropriate for measuring the volume of a large object, in this case a oil tank. It is the most appropriate out of the options given.
Option C should be the correct answer.
