Answer:
6
Step-by-step explanation:
If the sum of the digits of a number is divisible by 9, then the number is divisible by 9.
So 6+7+8+5+Δ+4 = Δ + 30 has to be divisable by 9, and of course 0≤Δ≤9
36 is divisable by 9, so Δ has to be 6.
First draw a rectangle. Label the longer sides as 20 feet long each. 20 + 20 = 40. that means there is 16 feet of fencing left for the shorter sides. This means that each of the shorter sides is 8 feet long <span />
