Answer:
The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: 
Step-by-step explanation:
We need to determine the value of c that will result in a perfect square trinomial.

Perfect square trinomial are of form: 
Now, the equation given is:

Looking at the term 6w, we can write it as 2(w)(3)
We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2
So, we will be adding (3)^2 on both sides

So, The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: 
Answer:
Infinitely many solutions.
Step-by-step explanation:
Step: Solve 2x + 8y = 6 for x:
2x + 8y = 6
2x + 8y + −8y =6 + −8y (Add -8y to both sides)
2x = −8y + 6
2x/2 = (-8y + 6)/2 (Divide both sides by 2)
x = −4y + 3
Step: Substitute −4y + 3 for x in −5x − 20y = −15:
−5x − 20y = −15
−5 (−4y + 3 ) −20y = −15
−15 = −15 (Simplify both sides of the equation)
−15 + 15 = −15 + 15 (Add 15 to both sides)
0 = 0
406 divided by 140 makes 2.9 multiply that 100 and you arrive at 290%. Hope this helps!
