Answer:
A
Step-by-step explanation:
2x2.5x3= 15
2x2.5x4.5=22.5
2.5x3x4=30
2.5x2x4=20
Answer:
6√10
Step-by-step explanation:
factorizing 6 and 60
6 = 2 x 3
60 = 2 x 2 x 3 x 5
hence
√6 · √60
= √ [ (2 x 3) · (2 x 2 x 3 x 5) ]
= √ (2· 2² · 3² · 5)
= √ (2² · 3²) x √(2·5)
= (2 · 3) x √10
= 6√10
The reflection across the x-axis only change the signal of the y coordinate. Hence, the new point is

.
2867.5 is bigger
Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first
If you ignore the decimal, your left with
290 vs 2867
2867 is much bigger than 290 so this is the answer
