Answer:
x = 11
Step-by-step explanation:
Given :
AB = x + 5
BC = 2(x - 3)
AB = BC
AB = BC
x + 5 = 2(x - 3)
x + 5 = 2x - 6
5 + 6 = 2x - x
11 = x
x = 11

<h3>What is an Equation ?</h3>
An equation is a mathematical statement that relates unknown variable to constants to determine their value.
The equation given is
(2x+3 ) / 7 Divided by 1 = 0
2x +3 = 0
2x = -3
x = -3/2
Therefore the value of x = -3/2 .
The complete equation is
(2x+3)/7

Answer:
Step-by-step explanation:
vector u=<(11-(-7),(-5-2)>=<18,-7>

The length of rectangular swimming pool = 25 feet
The width of the swimming pool = 12 feet
The pool is surrounded by a fence which is h feet from each side
So, length of fence becomes = 25+2h
Width of fence becomes = 12+2h
The expression for the length of the fence is 25+2h feet
2h because 'h' increases for both ends of the length of the pool.
