Rome's rivalry with Carthage for control of the western Mediterranean
Answer: Yuan Dynasty
Explanation:
Yuan Dynasty was China's first foreign-led dynasty and it was one of the great dynasties of that time. This is the term that is not belonging here because Tamerlane, Kublaii Khan, and Great Khan were leaders who led their territory and Yuan Dynasty was Dynasty that led China.
The Yuan Dynasty lasted from 1279 to 1368 which is about a hundred years of leadership and that is why this dynasty is also not fiting in these groups of leaders.

and examples are: eyewitness accounts, results of experiments, and statistical data
The correct answer is 6x + 4
Explanation:
The process to find the perimeter of shapes such as triangles, squares or rectangles is to determine the length of each side and add it. This implies in the case of the backyard the formula is length + length + width + width or 2 (length + side).
Additonally, in this rectangle the lenght is expressed by 2x -1 while the width is expressed by x + 3. Now, lets add these two expressions to find (lenght + side). Remember to add separately expressions containing letters and those containing only numbers:
2x - 1
+ x + 3 ___________________
3x +2
Finally, mutiply the expression by 2
Perimeter= 2 (lenght + width)
Perimeter = 2 (3x + 2)
Perimeter = 6x + 4
