Answer:
72 ![yd^{3}](https://tex.z-dn.net/?f=yd%5E%7B3%7D)
Step-by-step explanation:
Volume for a triangular prism =
a · c · h
A = Height. C = Width. H = Length.
A = 3 yd. C = 8 yd. H = 6 yd.
V = 114 yd.
V = 114 yd ÷ 2 yd = 72

Answer:
idk
Step-by-step explanation:
Ignoring the "?" in your question:
![5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}](https://tex.z-dn.net/?f=5k%2B10k%2B6%3D0%20%5Ciff%2015k%2B6%3D0%20%5Ciff%20k%3D-%5Cdfrac%7B6%7D%7B15%7D)
If the "?" is a squared symbol that wasn't caught:
![5k^2+10k+6=0](https://tex.z-dn.net/?f=5k%5E2%2B10k%2B6%3D0)
Use the quadratic formula
![x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x_%7B1%2C2%7D%3D%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
to get the solutions:
![x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}](https://tex.z-dn.net/?f=x_%7B1%2C2%7D%3D%5Cdfrac%7B-10%5Cpm%5Csqrt%7B100-120%7D%7D%7B10%7D)
as you can see, the discriminant is negative, so the equation has no solution.
The 3 it is the one the bottom left corner
