-1 times -1 is 1 and multiply that by another -1 and you get -1
-1 times -1 is 1 and you do that twice in the last option so that would be 1 and then multiply that by-1 and you get -1.
Answer: 2ayx4a
Step-by-step explanation:
1) First, we will need to simplify each equation:
4ax2y = 8axy
8axy = 8axy
2ayx4a = 8ayx4a
ax8y = 8axy
2) We can now see that 2ayx4a is not the same as the others.
Answer:
Step-by-step explanation:
ɸ = (1+√5)/2
The dimensions of the garden are either 5 ft by 5ɸ ft,
or 5 ft by 5/ɸ ft.
If the length is the shorter dimension, then the width is 5ɸ.
5ɸ ≅ 8.1 ft
If the length is the longer dimension, then the width is 5/ɸ.
5/ɸ ≅ 3.1
