Answer:
(3b+2)(3b-2)
Step-by-step explanation: It is the correct answer because we are factoring to the prime number.
The correct answer would be A. 21.5
a^2 + b^2 = c^2
so....
100 + 361 = c^2
The square root of 461 is 21.4709106 but you would round to 21.5
Answer: Devon, Tasha, Liza, Effon
Step-by-step explanation:
From the question, we are informed that four friends race their bikes down the street and that Evan finishes in 6.2 seconds, Devon in 6.0999 seconds, Liza in 6.188 seconds, and Tasha in 6.168 seconds.
The order that shows the friends' times from fastest to slowest is:
• Devon
• Tasha
• Liza
• Effon
Devon used 6.0999 seconds which is the fastest time, after then Tasha comes next with 6.168 seconds, then Liza with 6.188 seconds and lastly Effon with 6.2 seconds
What I believe they are asking is to find which of those is the simplified quadratic formula. The quadratic formula is -b (plus or minus) (√b²-4ac) all divided by 2a.
This formula works when the equation is set up as ax²+bx+c
