(7*8)+(7+8) = 56+15 = 71
Well, isn't that just a happy little question! The product of 7 and 8 is 56, which is different from the sum of 7 and 8, which is 15. Each operation brings its own unique result, just like how each brushstroke adds something special to a painting.
The sum of 1 and 7 is 8. That is, 1 + 7 = 8
8 + 7 = 15
76
(7*8)+(7+8) = 56+15 = 71
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.
You can find the sum of 8, 5, and 7, and then multiple that sum by 3, which is equal to 60.

To find two numbers whose sum is 8 and product is 7, we can set up the equations: ( x + y = 8 ) and ( xy = 7 ). From the first equation, we can express ( y ) as ( y = 8 - x ). Substituting this into the second equation gives ( x(8 - x) = 7 ), leading to the quadratic equation ( x^2 - 8x + 7 = 0 ). Solving this, we find the numbers are 7 and 1.
The sum is: 8
5 + 6 + 7 + 8 = 26
