Percy solved the equation x2 + 7x + 12 = 12. His work is shown below. Is Percy correct? Explain. 1. (x + 3)(x + 4) = 12 2. x + 3 = 12 or x + 4 = 12

{x +4} {x+3} =0

Step-by-step explanation:

The equation is given as :

x² + 7x + 12 =0

Find multiples of 12 that can add to give +12 3 * 4

The equation can then be written as;

x² + 3x + 4x + 12 = 0  factorize

x{ x + 3 } + 4 { x +3 } = 0

{x+4 } {x + 3} = 0

Answer : {x +4} {x+3} =0

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
