Answer:

r = 5   ; s = -9

Step-by-step explanation:

<h3>   Radical simplification.</h3>

First simplify √8  by

  • Prime factorize 8
  • Make pairs of similar factor
  • Take one factor out of every pair.

   \sf \sqrt{8}=\sqrt{2*2*2} = 2\sqrt{2}\\

\sf \dfrac{5+\sqrt{2}}{4}+\sqrt{8}= \dfrac{5+\sqrt{2}}{4}+ 2\sqrt{2}

          Find LCM and simplify

                     \sf = \dfrac{5+\sqrt{2}}{4}+\dfrac{2\sqrt{2}*4}{1*4}\\\\  =\dfrac{5+\sqrt{2}+8\sqrt{2}}{4} \ {\bf Combine \ like\  terms} \\\\ = \dfrac{5+9\sqrt{2}}{4}\\\\

 \sf \boxed{r=5}\\\\\boxed{s =-9}

My last question 30 pts plzzzzzzzzz help
yKpoI14uk [10]

Answer:

A) 48m + 12 and 3(2m + 4 + 14m)

B) 48m + 12 is equivalent to 6(m + 2 + 7m) because if you distribute the 6 to everything inside the parentheses, you get 6m + 12 + 42m. This can be simplified further by adding 6m and 42m together, leaving you with 48m + 12.  

C) m = 2

6(m + 2 + 7m)

6[2 + 2 + 7(2)]

6(4 + 14)

6(18) 1

108

3(2m + 4 + 14m)

3[2(2) + 4 + 14(2)]

3(4 + 4 + 28)

3(8 + 28) 3

(36) 108

108 = 108
