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.
You will need to find a common multiple of the two. For example:
2: 2, 4, 6
3: 3, 6
The common multple here is 6, so the answer is 6.

Answer:
128 feet
Step-by-step explanation:
So now we will substitute the values of T and π into the equation.
Divide both sides by 6.28
Square both sides.
Multiply both sides by 32
R - 3 < 5
r < 5 + 3
r < 8 Answer
