Let ​ x^2−12x=61 .​ What values make an equivalent number sentence after completing the square? Enter your answers in the boxes. HELP PLEASE

Answers

Answer 1
Answer: Complete the square:

x^2 - 12x + (-6)^2 - (-6)^2 = 61, or
      (x-6)^2            -36       = 61, or

x-6 = plus or minus sqrt(97), or

x = 6 plus or minus sqrt(97)
Answer 2
Answer: A=1 , b=-12 , c=61. B^2-(4 •a•c) = d
-12^2-(4•1•61)= d
X= (-b-sqr (d) ) / 2a or x=(-b+sqr (d) )/2a

14=2                       20=2                            25=5
 7=7                        10=2                              5=5  
 1=1                         5=5                               1=1        
so the one for 14     1=1                                so the answer for 25
would be 2*7           so the answer for 20      would be 5*5
                                would be 2*2*5 or 4*5

A salesperson at Crabby Crystal's Sea Life Store sells 2 fishing reels and 5 rods for $295. The next day, the salesperson sells 4 reels and 2 rods for $230. Find the cost of each. Write both equations and solve the system.

Answers

Answer:

1 fishing reel costs $35

1 rod costs $45

Step-by-step explanation:

let the cost of fishing reels be f and the cost of rods be r

2f + 5r = 295         Equation1

4f + 2r = 230         Equation2

multiply Equation1 by -2

-2(2f + 5r = 295 )

-4f -10r = -590       Equation3

Add Equations 2 & 3

4f + 2r = 230

-4f -10r = -590

------------------------

      -8r  = -360

         r = 45

substitute  r = 45 to any of the equations

I use 2f + 5r = 295

2f + 5(45) = 295

2f + 225 = 295

2f = 70

f = 35
