Other method:

zeros of numerator and denominator are x = -2 and x = 4.
Look at the second picture.
for x < -2 → x + 2 < 0 and x - 4 < 0
therefore 
for -2 < x < 4 → x + 2 > 0 and x - 4 < 0
therefore 
for x > 4 → x + 2 > 0 and x - 4 > 0
therefore 
<h3>Answer: B) -2 < x < 4</h3>
Answer:
3y + 4
Step-by-step explanation:
All odd integers are 2 units appart.Take for example the odd integers: 1, 3, 5, 7, 9, they all are 2 units apart from the next odd integer. Therefore, if 3y + 2 is an odd integer, then the next odd integer is 3y + 2 + 2 = 3y + 4. For example, if y = 1 , then the first odd integer is 3(1) + 2 = 5, and the odd integer that follows it is 3(1) + 4 = 7
Third option is the right answer:
−2x + 4y ≥ 0
The answer is C
call the length is a => the diagonal is a+1
11^2 + a^2=(a+1)^2
<=> 121 + a^2=a^2 + 2a +1
<=>120=2a
<=> a=60
So this is a special triangle. The 30-60-90 triangle rule states that if the short leg is y, then the hypotenuse is 2y and the long leg is y√3.
In this case, the short leg is 5√3 since that times √3 makes 15.
Now with the hypotenuse, just multiply 5√3 with 2, and your answer should be 10√3, or C.
