Answer:
x+3
Step-by-step explanation:
Area of a rectangle is 
.
We know the width, W, is 
and we know the area is 
.
Inputting this in our formula above we get:
L is a an expression such that when you multiply it to 
gives you 
.
is a difference of squares and can be factored using:
.
.
So L=x-3 and W=x+3.

Answer:
There are 3 adult tickets and 7 child tickets
Step-by-step explanation:
You are very close.
Let x = the number of adult tickets
Let y = number of child tickets
24.95x+ 15.95y = 186.50
The total number of tickets is 10
x+y =10
Subtract y from each side
x+y-y = 10-y
x =10-y
Substitute this into the first equation
24.95x+ 15.95y = 186.50
24.95(10-y) +15.95y = 186.50
Distribute
249.5 - 24.95y +15.95y =186.5
Combine like terms
249.5 - 9y = 186.50
Subtract 249.5 from each side
249.5-249.5 - 9y = 186.50-249.5
-9y =-63
Divide each side by -9
-9y/-9 = -63/-9
y =7
Now we need to find x
x+y =10
x+7 =10
Subtract 7 from each side
x+7-7 =10-7
x =3

Answer:
-8±10x
Step-by-step explanation:
you will follow BODMAS
B=bracket
O= off
D=division
M=multiplication
A=addition
S=subtraction
2×3=6
7×2=14
[6-14±10x-8]÷[x-2]
14±8=22
6-22=-16
[-16±10x]÷[x-2]=-8±10x
