Answer:
-2<x<4
Step-by-step explanation:
For , note that either the numerator or denominator is positive and the other must be negative for this inequality to be satisfied.
This means x+2>0 and x-4<0 or x+2<0 and x-4>0.
Lets look at the first scenario (x+2>0 and x-4<0)
x+2>0 and x-4<0
x>-2 and x<4
This means that -2<x<4.
Let’s look at the other scenario (x+2<0 and x-4>0)
x+2<0 and x-4>0
x<-2 and x>4
This means that x must be <-2 and >4 simualtaneously, which is impossible.
Therefore, this only occurs when -2<x<4.
I hope this helps! :)

Answer:
747ft
Step-by-step explanation:
split the shape into two rectangles. First one has length of 25 and has width of 10 because 20ft plus the 10ft ill give you the whole 30ft at the top. Multiply 25 by 10. So area for first shape is 250ft. Second shape area is 497 because you multiply 7 by 20. Then add 497 and 250 you get 747.
Answer:
A) 0 ≤ x ≥ 5
B) Number line is attached
C) Interval notation is; (0,5)
Step-by-step explanation:
We are told that the number is greater than zero and less than or equal to 5. If the number is x, then we can write the inequality as;
i) 0 ≤ x ≥ 5
ii) The solution graphed on a number line is attached.
iii) Since 0 ≤ x or x ≥ 5, then the interval notation is; (0,5)
