Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
Answer:
10
Step-by-step explanation:
We are taking 5m and dividing by 1/2 m
5 ÷ 1/2
Copy dot flip
5 * 2/1
10
We can get 10 pieces from the rope
Answer: B. 30
Step-by-step explanation:
First, you re-write the expression
6(-3.5) + 15(4) - 12(3/4)
Then multiply all the parts correctly.
-21 + 60 - 9
-21 + 60 = 39
-9
= 30
