For number 9 the answer would be 7 because in order to find area of objects you multiply length by width. So if the area is 49 and the length is 7, the width would have to be 7.
For number 10 the answer would be 6 because 20 times 6 is 120

Answer:
Jamal added 9 purple sox
Step-by-step explanation:
Here, we want to increase the probability
Initially the probability is;
18/(6 + 18 + 12) = 18/36 = 1/2 or 0.5 or 50%
So now, the probability is 60% which is 60/100 or 0.6
If we added x socks, then we number of purple socks become (18 + x)
The total number of x will be (36 + x)
so the probability now will be;
18+x/36 + x = 0.6
18 + x = 0.6(x + 36)
18 + x = 0.6x + 21.6
x-0.6x = 21.6-18
0.4x = 3.6
x = 3.6/0.4
x = 9
