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:
7x-6
Step-by-step explanation:
2(4x-5)-(x-4)
8x-10-x-(-4)
8x-10-x+4
7x-10+4
7x-6
Answer:
15 students at school
Step-by-step explanation:
So there is 50 students in total
First subtract that much with how much students have the flu
1/10 = 5/50
So 5 students have the flu
That leaves 45 students
Then subtract that much with the amount of students that are remaining are on the field trip
45 divided by 3 = 15
so 2/3 = 30/45 (they can both be multiplied and divided by 15)
so 30 of the 45 students are on the field trip
45 - 30 = 15
That means there are 15 students left over at school
