Answer:
B.
Step-by-step explanation:
Here the best method to solve is by substituting the end values of the set in each option , otherwise it will a time consuming problem.
Now substitute x=-4 in all the options
A.
16+8-8=16>0
so out of option A and C option C is correct.
B.
16-8-8=0 which means for the values of x>-4 is less than 0
Now substitute x=2 in all the options
A.
4-4-8=-8<0 . so option A and C both are incorrect.
B.
4+4-8=0 which means for the values of x<2 is less than 0
Therefore the correct option is B
Answer: x1 = 5
x2 = 1
Step-by-step explanation:

3. Complete the square
4. Solve for x
Use a ruler for this problem. Take a picture of the measurement & then I could help you.
Answer:
First vector
Second vector
Step-by-step explanation:
Given that
Vector a , a= 4 i + 5 j + 0 k
Vector b , b= 0 i + 1 j - 3 k
The orthogonal vector V is given as
V = a x b
V is the cross product of the above two vector which is orthogonal to the vectors a and b.
The unit vectors
First vector
Second vector
