Answer: 2,000 milliliters.
Step-by-step explanation:
Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:
1 liter + 1 liter = 2 liters of liquid.
Finally, we have to convert the result into milliliters.
Since 1 liter = 1000 liters
We have to multiply the liters drank by 1000.
2 x 1000 = 2,000 milliliters.

Answer:
<h2>Cubing both sides of an equation is reversible.</h2>
Step-by-step explanation:
Squaring both sides of an equation is irreversible, because the square power of negative number gives a positive result, but you can't have a negative base with a positive number, given that the square root of a negative number doesn't exist for real numbers.
In case of cubic powers, this action is reversible, because the cubic root of a negative number is also a negative number. For example
![\sqrt[3]{x} =-1](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%20%3D-1)
We cube both sides
![(\sqrt[3]{x} )^{3} =(-1)^{3} \\x=-1](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%7D%20%29%5E%7B3%7D%20%3D%28-1%29%5E%7B3%7D%20%5C%5Cx%3D-1)
If we want to reverse the equation to the beginning, we can do it, using a cubic root on each side
![\sqrt[3]{x}=\sqrt[3]{-1} \\\sqrt[3]{x}=-1](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%3D%5Csqrt%5B3%5D%7B-1%7D%20%5C%5C%5Csqrt%5B3%5D%7Bx%7D%3D-1)
There you have it, cubing both sides of an equation is reversible.
Answer:
The factored form of 16m²-9 = (4m+3)(4m-3)
Step-by-step explanation:
16m²-9
To find the factors of the expression, first you have to find out the perfect square of the terms:
4 is the perfect square of 16
∴4 is the number if multiplied two times wil give the product of 16.
m is the perfect square of m²
3 is the perfect square of 9
Then,
16m2-9 = (4m)² - (3)²
Now apply the perfect square formula:
a² - b² = (a+b)(a-b)
Therefore,
(4m)² - (3)² = (4m+3)(4m-3)
Thus the factored form of 16m²-9 = (4m+3)(4m-3) ....
