<span>The answers are b = 5 square root of 3; b = -5 square root of 3. f(b) = b^2 – 75. If f(b) = 0, then b^2 – 75 ) 0. b^2 = 75. b = √75. b = √(25 * 3). b = √25 * √3. b = √(5^2) * √3. Since √x is either -x or x, then √25 = √(5^2) is either -5 or 5. Therefore. b = -5√3 or b = 5√3.</span>

Answer:
The answer is 10 minutes.
Step-by-step explanation:
First, convert the known amount of time to a fraction.
6/21 (min over hot dogs).
Set up a proportion.
6/21 = m/35 (m being the number of minutes)
Cross multiply.
210 = 21m
Solve for m. (divide each side by 21)
m = 10
I hope this helps! :)
