Answer:
B
Step-by-step explanation:
Given inequality is open at - 3 and closed at 4. Therefore the required inequality would be:

Thus, option B is the correct answer.
Answer:
n =-19
Step-by-step explanation:
3* (n+7) = -36
Distribute
3n+21 = -36
Subtract 21 from each side
3n+21-21 = -36-21
3n = -57
Divide by 3
3n/3 = -57/3
n =-19
Answer:
x = 2
and
x = 3
Step-by-step explanation:
The function given is:

In this fraction, the bottom part is the denominator. We need to set it equal to 0 and solve for 2 values of x.

This is middle term factorization process. Hence the 2 solutions (roots) of the denominator is:
x = 2, 3
probably this would help.
