Please help! Will mark Brainliest if the answer given is correct! We call a number peachy if every digit in the number is either a $3$ or next to a 3 For example, the numbers 333,83, 303, and 3773 are all peachy, but the numbers 32523, 786, 340, and 3999 are not peachy.

How many positive 2digit numbers are peachy?

19

Step-by-step explanation:

All numbers which start with a 3 are peachy: {30, 31, 32, 33, 34, 35, 36, 37, 38 and 39}

All numbers which finish with a 3 are peachy: {03, 13, 23, 43, 53, 63, 73, 83 and 93} (33 was included in the previous list)

There are 10 numbers in the first list and 9 in the second list. Therefore, there are 19 peachy positive 2 digit numbers

no, because the sides are not congruent

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
