Find the sum of of LCM and GCF of 15, 35, 56

LCM sum: 3

GCF sum: 3

3 + 3 = 6

Step-by-step explanation:

Here I listed all the factors of each number:

15: 1, 3, 5, 15

35: 1, 5, 7, 35

56: 1, 2, 4, 7, 8, 14, 28, 56

As you can see, the LCM of these numbers is 1, since none of the other factors relate to all of the number's factors. This is also the only factor that all three of these numbers share.

1 + 1 + 1 = 3

The GCF of each of the numbers is also 1.

1 + 1 + 1 = 3

Hope this helps! :D

The point of intersection is the midpoint of the diagonal. The diagonals of a rectangle are the same length. These relationships tell you
2*AE = DB
2*(4x-12) = 7x-18 . . . . . substitute the given information
8x -24 = 7x -18 . . . . . . .eliminate parentheses
x - 24 = -18 . . . . . . . . . .subtract 7x
x = 6 . . . . . . . . . . . . . . . add 24

The value of x is 6.
