To find two numbers that multiply to 78 and add up to another number, we can use the quadratic formula. Let the two numbers be x and y. We have the equations xy = 78 and x + y = z. By substituting y = z - x into the first equation, we get x(z - x) = 78, which simplifies to x^2 - zx + 78 = 0. Using the quadratic formula, x = (z ± sqrt(z^2 - 4*78)) / 2. This formula gives us the possible values of x, and we can then find the corresponding values of y using the equation y = z - x.
6 times 13 equals 78 3 times 26 equals 78 2 times 39 equals 78 and 1 times 78 equals 78
9.75 times 8 equals 78.
2 x 39 equals 78
25 + 78 = 103
4+78=82-7=75

546 + 432 - 78 + 345 = 555
36 + 78 + 198 + 475 + 620 = 1,407
It is: 78 times 3,237 = 252,486
That equals 199
No.567 + 78 - 56 = 589
78 x 5 = 390
