I am using "x" but alphabet letter does not matter.
#9
Words: x is greater than or equal to -4
Algebra: x ≥ -4
Possible solutions: 0,1,2
#13
Words: x is greater than 0
Algebra: x > 0
Possible solutions: 1,2,3
103 stays because it is the whole number and the next number after the decimal is below 5.
103 is your answer.
Answer:
EF is parallel to HG or EH is parallel to FG. EF to HG is correct I think.
Step-by-step explanation:
Look at the markings on the lines.
Answer:
(B)15,36,39
Step-by-step explanation:
To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.
By Pythagoras Theorem: 
In 15,30,35

In 15,36,39

In 15, 20, 29

In 5,15,30

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.
