Answer:
20 and -20
20^2 = 400
(-20)^2=400 since two negative is positive
825 - 625i
Hope it’s right

Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
Graphing the 2 parabolas choice c is narrower.
c
Answer:
The solution of the inequality - 35x + 15 > 720 is
Step-by-step explanation:
Consider the given inequality
- 35x + 15 > 720
Subtract both side by 15 , we get
- 35x + 15 - 15 > 720 - 15
- 35x > 705
Multiply both sides by -1 (Reverse the inequality )
(-35x)(-1) < 705 (-1)
35x < -705
Now, divide both side by 35
Thus, the solution of the inequality - 35x + 15 > 720 is
