Answer: a
Step-by-step explanation:
none of the answers in b are divisible by 4
I’m so sorry I would try my best to answer but I can’t :(
For this case we have the following polynomial:
To find the value of c that completes the square, we use the following equation:
Where,
- <em>b: coefficient of the variable of degree 1
</em>
Substituting values we have:
Answer:
the value of c that completes the square is:
This would be considered a reasonable estimate because if you were to use estimation, you can round 289 to the nearest hundred (300), which is divisible by 60. When dividing 300 / 60, you will get 5 hours, which is 0.5 greater than 4.5 therefore making it a reasonable estimate. In addition, when actually dividing 289 / 60, you will get approximately 4.8 hours, which is close to the estimate, 4.5 hours.
