Answer:
The cube must be 21.125 feet long.
Step-by-step explanation:
David can completely cover a cube of side length equal to 2 feet, using 16 quarts of paint.
With this we make a conversion factor:
feet/quarts = 0.125 feet/quarts
This means that with each quart of paint you can paint a 0.125-foot long cube
We need to know how big is the length of a cube that can be covered with 169 quarts of paint
Then we use the conversion factor found earlier

The cube must be 21.125 feet long.
Answer:
The answer would be the first one
Step-by-step explanation:
tell me if im wrong
For this case we must factor
of the following expression:

By law of signs of multiplication it is fulfilled that:

So we have to:

Thus, by factoring we have:

Answer:

Statement: ALL square roots are irrational numbers.
Irrational is defined as a non-terminating real number.
✓4 = 2
2 is a terminating real number.
Therefore, 2 is rational.
The square root of 4 results in 2.
Therefore the square root of 4 results in a rational number.
Hence not all square roots result in irrational numbers.
