It is: 15+15 = 30

45, 60, and 75
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
45, 60, and 75
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26
The sum of addends 11 and 15 is: 11 + 15 = 26
The two numbers are 15 and 31. 15 + 31 = 46.
