WORTH 15 points! plz IM CRYING I NEED THIS DONE ASAP PLEASEEE

The lid will have a base area of 55 1/4 square inches. The long sides of the lid will each have an area of 17 square inches. The short sides of the lid will each have an area of 13 square inches. The total surface area of the lid will be 115 1/4 square inches.

So, for the base, you have w = 6.5 and l = 8.5. Area = 6.5 * 8.5 = 55.25 = 55 1/4.

For the long sides, you have l = 8.5 and h = 2. Area = 8.5 * 2 = 17

For the short sides, you have w = 6.5 and h = 2. Area = 6.5 * 2 = 13

For the total surface area, you have one base which is 55.25, you have two long sides which are 2 * 17 = 34, and you have two short sides which are 2 * 13 = 26. 55.25 + 34 + 26 = 115.25 = 115 1/4.

Answer:

The length of the long side is 147 ft

The length of the short side is 30 ft

Step-by-step explanation:

L=5s-3

s= 324-2L

324=2(5s-3)+s

distribute

324=10s-6+s

simplify

324=11s-6

add 6 to both sides

330=11s

divide by 11

30=s

Plug in the s value to determine the length of the long side

Suppose that G(X) = F(x + 2). Which statement best compares the graph of
nignag [31]

Answer:

A

Step-by-step explanation:

If you have to add 2 to X to get it back to the original, it started out 2 to the left.  (It would seem like it ought to be C, but when you add an subtract from the x value in functions, it's opposite of what you might think.)
