Please Help! A car traveling at 15 m/s starts to decelerate steadily. It comes to a complete stop in 10 seconds. What is it's acceleration?

initial velocity = 15 m/s

final velicity = 0 m/s

time required = 10sec

Formula is V = U + at

0 = 15 + a 10

-15 ÷ 10 = acc

acc = - 1.5 m/s^2

plz give branlist

B. -4, -3

Step-by-step explanation:

The equation x^(2) + 7x + 12 can be factored using the AC method resulting in

( x + 4 )( x + 3 ).  So x = -4, -3. You can use foil to check.
