The numbers are -95, -93, and -91.
How do you Factor 91 into prime numbers?
Divide by the smallest primes, 2,3,5,7,11,etc.If it divides without a remainder then it is a factor.Take the quotient and continue factoring by primes.91/2 no91/3 no91/5 no91/7=1313 is prime therefore 91=7 x 13
The sum of three integers is 69 If the first integer is doubled the sum is 77 If the second integer is doubled the sum is 91 Find the integers?
The first integer must equal 77 - 69 = 8 , since doubling it increases the sum by this amount. Similarly, the second integer must = 91 - 69 = 22. Then the third integer is 69 - 22 - 8 = 39.
