Answer:
6.2 Fahrenheit
Step-by-step explanation: I took the test hopes this helps (And sorry for being late)
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: Latisha
Answer:
20x+40
Step-by-step explanation:
Hey there! first, we multiply 5 x 4x = 20x. then we multiply 5 x 8 = 40
now we add them but in the 20x there is x so we can't add them but we can write them as 20x + 40
