Answer: AB+84
Step-by-step explanation:
Answer:
a: -3n+1
b:-5n-2
Step-by-step explanation:
a: it is -3+1 because you can see that the sequence is going down by 3, so it is the 3 times table, but because the number is 4, and 4 is 1 more than 3, you put plus one at the end. :)
b: similar to the last, it's going down by five, but it is two less this time, so you put minus two instead.
Hope this helps :),

Answer:
![C=27inch\ by\ 27inch](https://tex.z-dn.net/?f=C%3D27inch%5C%20by%5C%2027inch)
Step-by-step explanation:
Squares ![h=4inch](https://tex.z-dn.net/?f=h%3D4inch)
Volume ![v=1444in^3](https://tex.z-dn.net/?f=v%3D1444in%5E3)
Generally the equation for Volume of box is mathematically given by
![V=l^2h](https://tex.z-dn.net/?f=V%3Dl%5E2h)
![1444=l^2*4](https://tex.z-dn.net/?f=1444%3Dl%5E2%2A4)
![l^2=361](https://tex.z-dn.net/?f=l%5E2%3D361)
![l=19in](https://tex.z-dn.net/?f=l%3D19in)
Since
Length of cardboard is
![l_c=19+4+4](https://tex.z-dn.net/?f=l_c%3D19%2B4%2B4)
![l_c=27in](https://tex.z-dn.net/?f=l_c%3D27in)
Therefore
Dimensions of the piece of cardboard is
![C=27inch\ by\ 27inch](https://tex.z-dn.net/?f=C%3D27inch%5C%20by%5C%2027inch)
The school did reach the goal because if you add the games, concessions and donations you get $1232 and if you subtract 28 from it you get $1204 and if you subtract 75 from that you get $1129.
The correct option is B.. l hope it helped :)
