Faelyn grouped the terms and factored the gcf out of the groups of the polynomial 6x4 – 8x2 + 3x2 + 4. her work is shown.
step 1: (6x4 – 8x2) + (3x2 + 4)
step 2: 2x2(3x2 – 4) + 1(3x2 + 4)
faelyn noticed that she does not have a common factor. which accurately describes what faelyn should do next?

faelyn should realize that her work shows that the polynomial is prime.

faelyn should go back and regroup the terms in step 1 as (6x4 + 3x2) – (8x2 + 4).

in step 2, faelyn should factor only 2x out of the first expression.

faelyn should factor out a negative from one of the groups so the binomials will be the same.

Option 2 -  Faelyn should go back and regroup the terms in Step 1 as

Step-by-step explanation:

Given : Faelyn grouped the terms and factored the GCF out of the groups of the polynomial . Her work is shown.

Step 1:  

Step 2:

Faelyn noticed that she does not have a common factor.  

To find : Which accurately describes what Faelyn should do next?

Solution :

If we go back and regroup the factor in step 1 we may get the factors.

Step 1:  

Step 2:

Step 3:

So, Faelyn should go back and regroup the terms in Step 1 as

She get the factored form as :

Therefore,Option 2 is correct.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
