3x + 12 < 20
Their sum is three times the middle number.
4(n+12)
Five
Is this exactly how the problem was written?
3(x + 12)
3(x=12)
3x + 12 < 20
3(x + 12)
The sum of three times a number and its square is 10 more than 6 times a number?
Their sum is three times the middle number.
Statement:The sum of three times of a number and five.Assumption:Let us take the number be x.So, Three times the number = 3x.Equation: 3x+5
4(n+12)
"The sum of a number and three times another number is 18. find the numbers if their product is a maximum?"
3x+5x
-3
The question is ambiguous and the two possible answers are: Twelve times (a number and 5 times the number) = 12*(n + 5n) = 12*6n = 72n Twelve times a number amd five times the number = 12*n + 5*n = 17*n
