The numbers you use are
13.5 +13.5 +3 = 30
This is allowed because you can use any number and you can also repeat and in Brazil they right their decimals as 13,5 but in America it’s 13.5

What is the solution to this equation 4x + 2 ( x + 6 ) = 36
Margaret [11]

The answer is A. x=4.


Start off by distributing the parentheses into the equation.

4x+2(x+6)=36

4x+2x+12=26


Combine like terms.

4x+2x=6x

6x+12=36


Now solve the equation as normal. Begin by subtracting 12 from both sides to isolate the variable.

6x+12=36

-12 -12

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

6x = 24


Divide 6 on both sides to find x.

6x=24

---- -----

6 6

x=4


The solution to the equation is 4.

Furkat [3]
Each complete cleaning requires 6 drops of cleaner.  Let's convert that to ml:

6 drops     1 ml              3 ml cleaner
----------- * ------------- = ------------------- = 0.3 ml cleaner per cleaning
                 20 drops      10 cleanings

Recall that 1 bottle contains 30 ml cleaning fluid.

How many cleanings is one bottle of fluid good for?

1 bottle       0.3 ml
----------- = -----------   => x = 100 cleanings/bottle
      x            30 ml

Anyone know how to do it
Morgarella [4.7K]

Answer:

Surface area of cube = 6x²

surface area of cube = surface area of sphere

it means that 6x²=4πr²

x²=

\frac{4\pi {r}^{2}  }{6}  =  \frac{4 \pi9}{6}  =  \frac{4\pi3}{2}  = 6\pi

x =   \sqrt{6\pi}

\sqrt{6\pi}  =  \sqrt{k\pi}

6\pi = \pi \: k

k = 6
