Explanation:
First, group the 40 identical candies into 20 pairs. It doesn't matter how since the candies are identical. This grouping will ensure that any assigment will contain at least two candies.
Then think of the 20 groups a 20 beads on a string. We are looking to place 11 separators between them to obtain 12 segments, each with a varying number of beads between them. How many ways are there to place 11 separators to 19 potential spaces between beads? The asnwer is
If you would like to eliminate the z-term, you can do this using the following steps:
x + z = 6 /*(-2)
3x + 2z = 1
_____________
-2x -2z = -12
<span>3x + 2z = 1
</span><span>_____________
</span>-2x + 3x = -12 + 1
x = -11
The correct result would be <span>x + z = 6 /*(-2).</span>
b is equal to 1

Answer:
128 m^2
Step-by-step explanation:
You have 5 sides of a cube on the bottom with length 4
5 * 4x4 = 80 m^2
then four triangles on top
area of triangle = 1/2 base * height base = 4 height = 6
4 * 1/2 ( 4)(6) = 48 m^2
summed = 128 m^2
