Answer:
3 and 7
Step-by-step explanation:
You know from your multiplication tables that ...
21 = 1×21 = 3×7
There are no other factorizations of 21 using integers. You may notice that the sums of these factors are ...
1+21 = 22
3+7 = 10 . . . . . . this is the pair of numbers you are looking for
The two numbers are 3 and 7.
D. 1 unit
Because (5, -2) turns into (5, 2)
(5,3) so 5 minus 5 equals 0 and 3 minus 2 is 1
The answer is B. Flipping a coin does not influence your next flip. Also, the probability is 1/2*1/2*1/2, or 1/8.
