Determine the test statistic (t)
This is calculated as:

Calculate s using:

The equation becomes:




So:






Answer:
-20 < 4 - 2x (subtract 4 from both sides)

12> x (when you divide by a negative number, the inequality flips)
x< 12 ( I always put it so x is first)
so the answer is C
The length is 7 and the width is 3
Answer:
No solution
Step-by-step explanation:
The question is 4(3x-5)=12x-24
so we do the step:12x-20=12x-24
No solution.
