Answer:

RD = 162 cm

Step-by-step explanation:

LD = 2 RL = 2* 54 = 108

RD = RL + LD

RD = 54 + 108

RD = 162 cm

Factor completely 9ab + 12ax − 6b − 8x.
Len [333]
Okay so you split 9ab + 12ax - 6b - 8x 
<span>             into two 2-term polynomials </span>
              + 12ax + 9ab   and     - 6b - 8x
             doesn't look that good to me so lest try other one : 
             9ab + 12ax   and     - 6b - 8x
              looks good for now 

<span>      </span>      Pull out from each binomial separately
             9ab + 12ax   =   3a • (3b + 4x)
              - 6b - 8x   =    - 2 • (3b + 4x)

<span>     </span>      Add up to arrive at the desired factorization so now you have
            <span> (3a - 2) • (3b + 4x)

I really need help on my Study Island. If you are correct, I will give you Brainliest. Thanks!

Answer:

20

Step-by-step explanation:

You need to create two equations for each company and then set them equal to each other. The keywords base fee means you will pay this amount regardless, so this amount stays constant and it will be the constant in the equation.  The other keyword is per. Per will link the variable with the coefficient.

The first equation for company M:

y = 12x + 60

The second equation for company N:

y = 9x + 120

Set the equations equal to each other.

9x + 120 = 12x + 60

Solve for x. I am going to subtract 9x from both sides first.

9x - 9x + 120 = 12x -9x +60

120 = 3x +60

Now, I will subtract 60 from both sides.

120 - 60 = 3x + 60 - 60

60 = 3x

Finally, I will divide both sides by 3

60/3 = 3x/3

x = 20

20 is how many guests it will take for the total cost to be the same.

Solve for x.<br><br> −2x+3=15<br> Enter your answer in the box.<br><br> ​ x =
Elza [17]

Answer:

 x = -6

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -2x - 12  =   -2 • (x + 6)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x+6 = 0

Subtract  6  from both sides of the equation :

                     x = -6

One solution was found :

                  x = -6

Processing ends successfully
