so first u want to get a ruler to measure each sides, there gonna seem big at first so divide what you get on the ruler by 2 so its smaller, then do it for all sides.
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).
79-74 = 5. So the mean has increased by 5 points. (C)
The answer is reduction. This can be found by the size and number differences in the two quadrilaterals.
Step-by-step explanation:
2a = 10 because a = 5 and 2a means 2 × a which is the same as 2 × 5 and this equals 10.
