Percy solved the equation by expanding the expression on the left-hand side, and this is incorrect
<h3>How to determine the true solution?</h3>
The equation is given as:
x^2 + 7x + 12 = 12
The first step in solving the equation is to equate the equation to 0.
i.e.
x^2 + 7x + 12 - 12 = 0
This given
x^2 + 7x = 0
From the question, Percy solved the equation by expanding the expression on the left-hand side
Hence, Percy's solution is incorrect

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:
x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−12=−4x+23
Step 1: Add 4x to both sides.
3x−12+4x=−4x+23+4x
7x−12=23
Step 2: Add 12 to both sides.
7x−12+12=23+12
7x=35
Step 3: Divide both sides by 7.
7x
7
=

Answer:
x=5
The length of the ladder is 25 feet.
<u>Explanation:</u>
Height of the House, h = 24 feet
Distance between the house and the ladder, b = 7 feet
length of the ladder, x = ?
The house makes 90° with the base of the ladder.
Using pythagoras theorm,
x² = h² + b²
x² = (24)² + (7)²
x = √625
x = 25
Therefore, the length of the ladder is 25 feet.
