Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition, when three real numbers are added, it makes no difference which two are added first.
(a + b) + c = a + (b + c)
Therefore, 8 + (2 + 6) = (8 + 2) + 6 is an example of the Associative Property of Addition.

Pythagoras Theroem.
Leg₁²+leg₂²=hypotenuse²
Data:
Leg₁=48
hypotneuse=80
(48)²+ leg₂²=(80)²
2304+leg₂²=6400
leg₂²=6400-2304
leg₂²=4096
leg₂=√4096
leg₂=64
Answer: B. 64
Let's round 2141 to 2000
2000 times 8=1000 times 2 times 8=1000 times 16=16000
estimate would be 16000
Deceleration is always the opposite of Acceleration so is negative. So deceleration =-2.2m/s^2
