Answer: i think 4
Step-by-step explanation:
Answer:
If you round two decimal places, it should be 9.
Step-by-step explanation:
2 (x + 4) is equivalent to 2x + 8 NOT 2 (x + 4) + 4
Answer:
1). 
2). 
Step-by-step explanation:
In this question we have to write the fractions in the factored form.
Rational expressions are
and
.
1).
Factored form of the denominator (x² - x - 12) = x² - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
= (x + 3)(x - 4)
Therefore. 
2). 
Factored form of the denominator (x² - 16) = (x - 4)(x + 4)
[Since (a²- b²) = (a - b)(a + b)]
Therefore,
