Jordy bought 3 sets of 100 stamps, 2 sets of 20 stamps, 4 sets of 12 stamps, and 1 set of 10 stamps. How many stamps did Jordy buy?
A. 370
B. 378
C. 398
D. 410

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
