A ladder rests against the top of a wall. The head of a person 6 feet tall just touches the ladder. The person is 12 feet from the wall and 6 feet from the foot of the ladder. Find the height of the wall.

18

Step-by-step explanation:

the person is 12 feet away from the wall and 6 feet away from the ladder, meaning the ladder is 18 feet away

since the person is 6 ft and is 6 ft away from the ladder and is touching it, you can make a proportion

6/6 = x/18

and when u solve u get x is 18

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
