Move all terms to one side
4w^2 + 49 + 28w = 0
Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7
(2w)^2 + 2(2w)(7) + 7^2 = 0
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
(2w + 7)^2 = 0
Take the square root of both sides
3w + 7 = 0
Subtract 7 from both sides
2w = -7
Divide both sides by 2
<u>w = -7/2</u>

Answer:
C: S≤35h+42
Step-by-step explanation:
Since the competitor charges $35 per hour PLUS 42(individually), it is 35h+42.
Suzzette's charges should be NO MORE than the competitor, so it could include the SAME amount too. So S(suzzette) is lesser than Or equal to 35h+42.
The answer is C, S≤35h+42
