Use PEMDAS - order of operations

First work out the the parentheses:-
21 + 4(3^2 - 5)
= 21 + 4(9 - 5)
= 21 + 4*4                           Now the multiplication:-
=  21 + 16
= 37

algol [13]

Answer:

Step-by-step explanation:

21-26. a = v - u / t

=> a = 47 - 19 / 5

=> a = 28 / 5

=> a = 5.6 m/s²

27-32. avg. speed = distance / time

=> 40 m / 10 s

=> 4 m/s

33-38. velocity = distance / time

=> v = 150 / 40

=> v = 15 / 4

=> v = 3.75 m/s
