We want to verify that x² + x - 12 = (x - 3)(x + 4)
We can prove this by factoring the left side and showing that it is equal to the Right side.
We should find factors of -12 that sum to +1.
-12 = 1 x -12 Sum = 1 - 12 = -11 No
-12 = 2 x -6 Sum = 2 - 6 = -4 No
-12 = 3 x -4 Sum = 3 - 4 = -1 No
-12 = 4 x -3 Sum = 4 - 3 = 1 Yes
Therefore
x² + x - 12 = (x - 3)(x + 4) which is equal to the Right side.
Latisha is correct because
4(-3) = -12, and
-3 + 4 = 1

Answer:
2.25 or 2 1/4
Step-by-step explanation:
Easy. you add them like regular numbers. 1/4 + 2 = 0.25 + 2 =2.25 and/or 2 1/4
Can you please show the line plot or send a picture through my profile. I may be able to help you then.
Because 1/3 is bigger than 1/4. 1/3 means it was cut into 3 parts, 1/4 means it was cut into 4 parts. The fewer parts you cut, the bigger each part is.
