A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Is 20 an abundant deficient or perfect number?

Abundent


Is the number 20 a deficient number?

No; 20 is an abundant number. S = {1, 2, 4, 5, 10} is the set of all positive divisors of 20, excluding itself. The sum of these divisors = 1+2+4+5+10=22 which is greater than 20. Therefore 20 is an abundant number, not a deficient number. When the sum exceeds the number, the number is abundant. When the sum equals the number, the number is perfect. When the sum is less than the number, the number is deficient.


Is 34 an abundant perfect or a deficient number?

To find out if a number is abundant, perfect or deficient, you first need to split it into its prime factors: 34 = 2x17 The next step would be to find any combinations, but as we have only 2 prime factors, those are the two we'll work with. You add these together, with 1, and get 20. When this sums to less than the original number it's a deficient number. 20 is less than 34, and so 34 is a deficient number.


Is 20 a perfect number?

No it is not. The closest perfect number to it is 28. The divisors of 20 are 1,2,4,5,10 those add up to more than 20 so 20 is an abundant number.

Is 20 an abundant number?

Yes 20 is an ABUNDANT number because 1+2+4+5+10=22 and that is more than 20. PS how to find and ABUNDANT number is to add up all its factors. :)

Is the number a perfect square?

Why is 20 a abundant number?

Let S be the set of the positive divisors of 20, excluding 20. S = {1, 2, 4, 5, 10} The sum of all the elements of S = 1 + 2 + 4 + 5 + 10 = 22 > 20. Therefore, 20 is an abundant number.
