Answer: D) 24
===============================================
Explanation:
Find the prime factorization of each value given
- 28 = 2*2*7
- 15 = 3*5
- 21 = 3*7
- 24 = 2*2*3
Of the four choices, only 24 has 2*3 = 6 as a factor. Something like 15 doesn't have 6 as a factor, so there's no way the GCF of 15 and 18 is equal to 6.
Focusing on 24 and 18, we see that
which shows that 6 is the GCF of 24 and 18.

Step-by-step explanation:

Discriminant

If the discriminant is a negative number then the roots of the equation are imaginary

So, the two solutions are

42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
