Which set of numbers represents solutions of the inequality m>20?

zlopas [31]

Answer:

{21, 22, 23, 24}

Step-by-step explanation:

m>20 means that m is greater or more than 20, therefore 21, 22, 23, and 24 are all greater than 20 so that is the answer.

A perfect square must be hidden within all of those radicands in order to simplify them down to what the answer is. $\sqrt{192}= \sqrt{64*3}= 8\sqrt{3}$ . $\sqrt{80}= \sqrt{16*5}=4 \sqrt{5}$ . $\sqrt{12288}= \sqrt{4096*3}=64 \sqrt{3}$ . The rules for adding radicals is that the index has to be the same (all of our indexes are 2 since we have square roots), and the radicands have to be the same. In other words, we cannot add the square root of 4 to the square root of 5. They either both have to be 4 or they both have to be 5. So here's what we have thus far: $8 \sqrt{3}+4 \sqrt{5}+64 \sqrt{3}$ . We can add $8 \sqrt{3}$ and $64 \sqrt{3}$ to get $72 \sqrt{3}$ . That means as far as our answer goes, A = 72 and B = 4, or (72, 4), choice a.

The GCF of numbers or expressions is the highest factor, common in both numbers or expressions.

The GCF of $24x^2y$ and $34x^2y$ is $2x^2y$
