It depends on how you count them. If you describe them by their dimensions, lowest one first, you can have
1 x 1 x 18
1 x 2 x 9
1 x 3 x 6
2 x 3 x 3
Of course, these dimensions can be put in any order.
27.0 ft should be the answer
In simplified form, the answer would be -16x+51
Answer:
![(h,k)=(-2,-1)](https://tex.z-dn.net/?f=%28h%2Ck%29%3D%28-2%2C-1%29)
Step-by-step explanation:
![y=-x^{2} -4x-3\\y=-(x^2+4x+3)\\y=-(x^2+4x+3+1)-1\\y=-(x^2+4x+4)-1\\y=-(x+2)^2-1\\y=a(x-h)^2+k](https://tex.z-dn.net/?f=y%3D-x%5E%7B2%7D%20-4x-3%5C%5Cy%3D-%28x%5E2%2B4x%2B3%29%5C%5Cy%3D-%28x%5E2%2B4x%2B3%2B1%29-1%5C%5Cy%3D-%28x%5E2%2B4x%2B4%29-1%5C%5Cy%3D-%28x%2B2%29%5E2-1%5C%5Cy%3Da%28x-h%29%5E2%2Bk)
1 is b and it would be 164
