Step-by-step explanation:
Given
The function is 
To make it a perfect square, compare it with 
Here,

So, c must be square of b i.e. 9

Therefore, value of c is 9.
Answer:
= 7
Step-by-step explanation:
get it right! hope you get it right!\
When two lines cross like this, sum of measures of opposite angles is 180.
this means that:
measure angle AEC + measure angle BED = 180
4x-40 + x+50 = 180
5x +10 = 180
5x = 170
x = 34
therefore:
measure angle AEC = 4x-40 = 4(34)-40 = 96
measure angle BED = x+50 = 34+50 = 84
Answer:
to make sure you understand the question
Step-by-step explanation:
The time taken is 
<h3>Distances</h3>
Given the following information:
- Distance from Neptune to Mars =

- Time is taken =

Get the time taken:
Time = Distance/Speed
Time = 
Time = 0.89 * 10^5
Time = 8.9 * 10^4hrs
Hence the time taken is
