The width is 3m because 3*7 is 21m^2. Also they said the length is 4 more than the width (3+4=7)
D. Distributive Property
The distributive property allow you to multiply a sum by multiplying each addend separately.
The answer is A
Have to add characters to get to 20
SOLUTION
From the question, we want to find the probability of selecting a slip of paper with the letter t on it, then selecting the letter r, with replacement.
This means the probability of selecting t and r.
That is

There are 12 letters (total outcomes). And there are 2r and 2t.
So probability becomes

Hence the answer is
The bottom answer m y = m h
