For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16
21d = 42
d = 42/21
d = 2 :)))
I hope this is helpful
have a nice day
Hi there!

Use the kinematic equation to solve for acceleration:

Where:
vf = final velocity
vi = initial velocity
t = time
Plug in the given values:

The answer is choice A- 68
Isn’t it h?
extra words so i can actually post this reply
