License plates are made using 3 letters followed by 2 digits. how many plates can be made if repetition of letters and digits is allowed? a) 1,757,600b) 11,881,376c) 100,000d) 175,760

A) 1,757,600

Step-by-step explanation:

26x26x26x10x10 = 1,757,600

There are 26 letters that can repeat and there are 10 numbers (0-9) that can repeat.

1,200 cm3

Step-by-step explanation:

p = 2l + 2w

60 = 2(3x + 2) + 2(2x - 2)

60 = 6x + 4 + 4x - 4

60 = 10x

x = 6

Thus,

l = 3x + 2 = 3(6) + 2 = 20

w = 2x - 2 = 2(6) - 2 = 10

h = x = 6

V = lwh = (20)(10)(6) = 1,200 cm3
