Lets solve your equation step by step:

(4k + 5)(k + 1) = 0



Step 1: Simplify both sides of the equation:

4k^2 + 9k + 5 = 0



Step 2: Factor left side of equation:

(4k + 5)(k + 1) = 0



Step 3: Set factors equal to 0:


4k + 5 = 0 or k + 1 = 0


k = - 5/4 or k = - 1






Answer: k = - 5/4 or k = - 1








Hope that helps!!!! ( Answer: k = -5/4 or k = -1)

Use distributive property to get 4k^2 +9k+5 and factor it from there. You should get (4k+5)(4k+4).

The difference of the two numbers is 5 and their quotient is 2​
bazaltina [42]

Answer:

The difference of two numbers is 5:

x - y = 5

Their quotient is 2:

x/y = 2

Since x/y = 2 then x = 2y

Substituting into x-y=5 gives:

2y - y = 5

y = 5

x = 2y = 2(5) = 10

Your numbers are 10 and 5

Hope it helps

Select steps that could be used to solve the equation 1 + 3x = -x + 4.
Olegator [25]

Answer:

A, C & D

Step-by-step explanation:

A) 1 + 3x = -x + 4  {subtract 1}

  1 + 3x -1 = -x + 4 - 1

       3x     = -x + 3         {add x}

     3x + x = -x + 3 + x

        4x    = 3       {Divide by 4}

       4x/x = 3/4

x = 3/4

C) 1 + 3x = -x +4            {Add x}

  1+ 3x + x = - x +4 + x      

   1 + 4x  = 4    {subtract 1}

        4x = 4 - 1

        4x = 3   {Divide by 4}

D) 1 + 3x = -x + 4        { Subtract 3x}

         1    = -x + 4 -3x

         1 = -4x + 4          Subtract 4}

      1 - 4 = -4x

        -3 = -4x              {Divide by -4}

       -3/-4 = x

x = 3/4  

          x = 3/4
