Answer:
uv - 10u
Step-by-step explanation:
To distribute a problem, you have to multiply what is on the outside of the parenthesis with what is on the inside. 
u · v = uv
u · -10 = -10u
Combined, u(v - 10) = uv - 10u.

Answer:
It is a perfect square. Explanation below.
Explanation:
Perfect squares are of the form 
(
a
+
b
)
2
=
a
2
+
2
a
b
+
b
2
. In polynomials of x, the a-term is always x.(
(
x
+
c
)
2
=
x
2
+
2
c
x
+
c
2
)
x
2
+
8
x
+
16
 is the given trinomial. Notice that the first term and the constant are both perfect squares: 
x
2
 is the square of x and 16 is the square of 4.
So we find that the first and last terms correspond to our expansion. Now we must check if the middle term, 
8
x
 is of the form 
2
c
x
.
The middle term is twice the constant times x, so it is 
2
×
4
×
x
=
8
x
.
Okay, we found out that the trinomial is of the form 
(
x
+
c
)
2
, where 
x
=
x
and
c
=
4
.
Let us rewrite it as 
x
2
+
8
x
+
16
=
(
x
+
4
)
2
. Now we can say it is a perfect square, as it is the square of 
(
x
+
4
)
.
 
        
             
        
        
            
            
                Which stem-and-leaf plot represents the data 80, 81, 91, 92, 66, 55, 54, 30, 55, 79, 78? 
                const2013 [10]             
         
        
Convert the given data into ascending order.
30,54,55,55,66,78,79,80,81,91,92
Here the minimum value is 30 and maximum is 92.
Total counts=11
Now plot the data.
Stem | Leaf
3       |  0
5       | 4 5 5
6       | 6
7       | 8 9 
8       | 0 1
9       | 1 2
This is the required stem leaf plot.
