B: m is less than or equal to 3
2: 10 pm
1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10 <--width+width
4+4=8 <---length + length
10+8=18 <--total perimeter
18 * 9=162in^2 <--multiplied the height +perimeter of base
Lateral Area=162in^2
2) Same concept as the previous one
Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2
Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2

Answer:
Probably A, can't see all of D
Step-by-step explanation:
I can't see the last of D, so I will still try.
A function means that each x only goes to one y, but each y can have multiple xs going to it. If that's hard to understand, on the table, if you have two of the same xs on the x side, they HAVE to have the same y on the y side. Simple as that.
Right away, A looks right since it doesn't repeat anything on the x side, it has 4, 5, 6 and 7. Let's look at the others.
B repeats 3, but the ys are different, one has 10 and one has 30, so this isn't a function. They would both have to be 10 or 30 or some other number.
C repeats -5 and both have a different y, 2 and 3, so not a function
D I can only see the first two x entries so I can't be sure, so maybe you can tell. If there is any repeat int he x side and the corresponding y side isn't the same then it also isn't the function. i have to assume there is a repeat though.
