2*(7 + 15) = 2*22 = 44
It is: 15+15 = 30
2x + 7
?=2n+7
2*(15 + N)
2n + 15 = 37
2(n+7)
The two numbers with the sum of 15 and the product of 56 are: 7 + 8 = 15 7 x 8 = 56
8 + 7 = 15
-7
To find one half the sum of 8 and 7, first calculate the sum: 8 + 7 equals 15. Then, take one half of 15, which is 15 divided by 2. This gives you 7.5. Therefore, one half the sum of 8 and 7 is 7.5.
n = number 2(n + 15) ======
