No, because the lasts line of the work is not true. 5 and 11 are not equal.
This problem shows 2/5 times 1/3 (Choice C). You can determine this by looking at the number of complete columns that are shaded out of the total number of columns(2/5). The look at how many complete rows are shaded out of the total number of rows shown(1/3). The overlapping part becomes the answer to the multiplication of these 2 fractions.
(a^3 - 2a + 5) - (4a^3 - 5a^2 + a - 2)
=a^3 - 2a + 5 - 4a^3 + 5a^2 - a + 2
= -3a^3 + 5a^2 - 3a + 7
The measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.
<h3>What is the Unit conversion?</h3>
Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm,
Though the real measurement is still the same the units and numerical values have been changed.
As it is given, the pool's volume or the amount of water in the pool is equal to 2.3×10⁴ units.
We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.
Hence, the measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.
