4u-24 because you have to take 4 and multiply it by your things inside your parentheses
Answer:
Expected value: 3/7
Change landing on purple to -1.5
Step-by-step explanation:
Expected value
=3(1/7) + 1(2/7) + 0(2/7) - 1(2/7) = 3/7

Answer:
The question confused me a bit because of the different numbers.
The answer would be
w(2 * 18), which would be the same as choice a if the numbers weren't different.
Step-by-step explanation:
Answer:
See proof below
Step-by-step explanation:
One way to solve this problem is to "add a zero" to complete the required squares in the expression of xy.
Let 
and 
with 
. Multiplying the two equations with the distributive law and reordering the result with the commutative law, we get 
Now, note that 
by the commutativity of rational integers. Add this convenient zero the the previous equation to obtain 
, thus xy is the sum of the squares of 
.
