When a mantis shrimp strikes, its arm-club gets up to a velocity of 23 m/s moving away from its body. Scientists calculate the acceleration at 100,000 m/s/s.
How long does it take the arm-club to get to 23 m/s?

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !

yeah i know the problem you need. i am taking it right now. the answer is step 3
