X + 7 = 49
=======
The number is 4 (4+3) * (4+3) = 49 (4+2) * (4+2) = 36 49 - 36 = 13
49 is a composite number because it has more than two factors
49 is a composite number because it has more than two factors and it is also a square number
49 - 17, D16
65+49-39=75
The number is 4 (4+3) * (4+3) = 49 (4+2) * (4+2) = 36 49 - 36 = 13
2a+3>49

Let the number be x and so: 2x+3 > 49
49 - 17, D16
65+49-39=75
49 is a composite number because it has more than two factors. The three factors of 49 are 1, 7, and 49.
A perfect number is one with factors (apart from itself) that sum to give the original number. An abundant number is one where this sum is greater than the original number. A deficient number is one where the sum is less than the original number. The factors of 75 are 1, 3, 5, 15 and 25. The sum of these numbers is 49. Thus 75 is a deficient number.
