B) 7 would make it true, since both 42/54 and 7/9= 0.77 repeating
(6b + 42)(b - 3)
To check the answer, use the method FOIL.
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:
D)
3* (2 x 8) = 3 * (8 x 2)
Step-by-step explanation:
multiplication distributes over addition.
