What is the missing constant term in the perfect square that starts with x 2 +14x
1 answer:
Okay, let me explain.
Basically, you need to complete the square.
So you have, +14x+__________ to equal a perfect square.
Your middle term is 14. So, what you need to do is divide fourteen by 2 which equals 7. What does 7*7 or 7 squared equal? It equals 49.
The missing constant term is 49.
I hope this helped; feel free to ask any follow-up questions.

Answer:
The value of x is .
Step-by-step explanation:
Please look at the figure attached to get more clear solution.
We have given:
FG||CB
And the line that cut the parallel line is transversal so, here BA is transversal
And alternate interior angles on transverse line are equal
So, ∠1=∠4
And ∠4=
Hence, ∠1=∠4=
And On FG the sum of angles will be
∠3+∠2+∠1=
+∠2+
=
Hence, ∠2=
Now, we know that the sum of interior angles is equal to the exterior angle:
Therefore, ∠2+∠5=∠6+∠7
On simplification we get:
Hence, the value of x is .
