Answer:
$25
Step-by-step explanation:
well you have to identify what the method is first.
He is basically pricing things by the count of 5. So, you can assume that it would cost $25.
Idk, this is a weird problem
check attached file it has the answers
3x =-18
X= -12
Answer:
D
Step-by-step explanation:
The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.
The entry in the 
row (start counting rows from 0) and 
column (start counting columns from 0) of Pascal's triangle is denoted by
Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.
Hence,
Answer: 376 cm^2
Step-by-step explanation:
First you would double all the dimensions:
l = 5 cm x 2 = 10 cm
w = 4 cm x 2 = 8 cm
h = 3 cm x 2 = 6 cm
The formula for finding the surface area of a rectangular prism is A=2(wl+hl+hw)
Substitute the values:
A=2(8*10+6*10+6*8)
Solve using PEMDAS:
A=2(80+60+48)
A=2(188)
A=376
Surface area is always in units^2:
376 cm^2
