There are no such numbers.

only 59 is prime. rest are composite numbers

89

The sum means the result of adding the numbers. Therefore the sum of 20 and 15 is 35. 5 times 35 is 175 - therefore 5 multiplied by the sum of 20 and 15 is 175.

There aren't any integers. Nearest I can get is -2.89 & -12.11. Sum is -15 and product is 34.998

The prime numbers from 35 to 60 are 37,41,43,47,53,59.

5, 15, 25, 35

17 19 23 29 31

If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)

5 35/5=7 15/5=3 3 and 7 are prime numbers

No because 11 is a prime number but the rest of them are composite numbers.
