Answer:

Total surface area of the pyramid is 236.16cm² and the expression is

2bs + s²

Step-by-step explanation:

Total surface area of a square pyramid is expressed as;

TSA = 2bs + Base Area

b is the side length  of the base = 8.2cm

s is the slant height of the triangular side = 10.3cm

Base area = s²

Base area = 8.2²

Base area = 67.24cm²

TSA = 2(8.2)(10.3)+67.24

TSA = 168.92+67.24

TSA = 236.16cm²

Hence the total surface area of the pyramid is 236.16cm² and the expression is 2bs + s²

I have a word problem with a pattern. I just can't figure it out. - On the first night, Kim's mom gave her a nickel, on the seco
denpristay [2]
1st night Nickel - 5 pennies
2nd night 5 nickels - 25 pennies
3rd night 14 nickels - 70 pennies
4th night 30 nickels - 150 pennies
5th night 46 nickels
6th night 78 nickels
7th night 126 nickels
8th night 206 nickels
9th night 334 nickels
10th night 542 nickels

So her mother would give Kim 542 nickels on the 10th night.

Differences between number of nickels: 4, 9, 16

9 - 4 = 5
16 - 9 = 7

The pattern is Kim's mom gives her child two more nickels plus the amount of nickels she got the day before.

This was a little tricky so I don't know if this is right but I hope this helps you!

So, the answer is neither
