The second one is
the right answer.
(i think i’m right i’m sorry if i’m not !)
The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters
Answer:
A.
Step-by-step explanation:
the second number is just 10 more than the first
Simplify (18+-2) to 90-(16)(-3)
Multiply (16)(-3) -> -48
Simplify 90-48
Answer is 42

Answer:
x < -√6 or √6 < x
Step-by-step explanation:
You want ...
2x^2 -3 > 9
2x^2 > 12 . . . . . add 3
x^2 > 6 . . . . . . . divide by 2
|x| > √6 . . . . . . . take the square root
This resolves into two disjoint sets:
x < -√6 or √6 < x
__
In set notation, this might be ...
{x | x < -√6 ∪ √6 < x}
