Her average time was 8.1 minutes per mile.
Step-by-step explanation:
(3x^2+9x-6) - (2x^3-4x^2+6x-4)
Short Answer
2x^3+7x^2+3x-2
Step by Step
1.)2x^3 doesn’t subtract from anything because there are no other trinomials
2.)3x^2 - (-)4x^2 = 7x^2 because a double negative cancels out and you end up adding them
3.)9x-6x=3x
4.)-6 - (-)4 = -2 because double negatives cancel out into addition
So twin primes are prime numbers that have a difference of 2. The ones between 25 and 55 are (29,31) and(41,43). Hope that helps
