1) Always be polite and professional.
2) Specifically address the points that you disagree with.
3) Provide Evidence.
4) Close with a brief summary of your rebuttal.
<span>272mi/68mi/hr= 4 hr
Example:
Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario. </span>
<span>Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds </span>
<span>Solution: </span>
<span>A = 45 m/s – 15m/s / 6s </span>
A = 5m/s^2<span>

Answer: 15h^2 + 26h -21
Step-by-step explanation:
Use the foil method. Multiply in this order
First, 5h*3h= 15h^2
outer, 5h*7 = 35h
inner, -3*3h= -9h
last, -3*7= -21
Now add them all together
15h^2 + 35h + -9h + -21
Combine like terms
15h^2 + 26h -21
24 divided by 56 will give you the answer.
= 0.42
Answer : 42%
