Display board measurements = 10ft by 6ft
So all the sides would be 10ft, 10ft, 6ft, 6ft
Add them all together= 32ft
Ribbon length would need to be 32ft long
Answer:
b
Step-by-step explanation:
It's b because if you plug in 1 for d in each of the equations, you get 99 in b only.
The volume of a shape is the amount of space in it.

2 t + 2 (1 - 3 t)
= 2t + 2 - 6t (distributive property)
= 2 - 4t (combine like terms)
Replace x with -1, and y = 9
Therefore, (x²y)/-7 becomes (-1² · 9)/-7
-1² is just 1, and 1 × 9 is just equal to 9, so your final answer is -9/7.
