The sum of x and y=x+y
their product=xy
Therefore the expression is
(x+y)-(xy)
Answer and Explanation
<h2>0</h2>
<em>This is because they are both the same opposite number, and you are adding.</em>
But, if it was, then it would be or .
<em>So, the answer is 0.</em>

Answer:
u = -1
Step-by-step explanation:
5(u+1)-u=3(u-1)+7
distributive property
5u + 6 = 3u - 3 + 7
simplify
5u + 6 = 3u + 4
-3u on both sides
2u + 6 = 4
-6 on both sides
2u = -2
divide 2 on both sides
u = -1
Answer:
see in the picture, we have:
P is the midpoint of AB
Q is the midpoint of CD
=> PQ is the median line of the trapezoid ABCD
=> PQ = (BC + AD)/2 = (54 + 33)/2 = 43.5
