The distance between them
This is calculated as:

So, we have:




12.25x2=24.50 (width x2)
24.50-1=23.50 (length)
Area= LxW
=23.50x12.25
=287.88 feet

Answer:
3ac + bc
Step-by-step explanation:
c(3a + b)
Distribute (multiply) the c to the numbers in the parentheses.
c * 3a = 3ac c * b = bc
3ac + bc
x=23
Simplifying
(3x + -50) + (7x)
Reorder the terms:
(-50 + 3x) + (7x)
Remove parenthesis around (-50 + 3x)
-50 + 3x + (7x) =
Combine like terms: 3x + (7x)
-50 + 10x
Solving
-50 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '50' to each side of the equation.
-50 + 50 + 10x = 180 + 50
Combine like terms: -50 + 50 = 0
0 + 10x = 180 + 50
10x = 180 + 50
Combine like terms: 180 + 50 = 230
10x = 230
Divide each side by '10'.
Simplifying
x = 23
