its k=2

One solution was found :

                  k = 2

Step by step solution :

Step  1  :

           1

Simplify   —

           3

Equation at the end of step  1  :

       2          1      

 ((k • —) +  (k • —)) -  2  = 0

       3          3      

Step  2  :

           2

Simplify   —

           3

Equation at the end of step  2  :

       2     k    

 ((k • —) +  —) -  2  = 0

       3     3    

Step  3  :

Adding fractions which have a common denominator :

    Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2k + k     3k

——————  =  ——

  3        3

Reducing to Lowest Terms :

   The above result can still be reduced :

    3k    

    —— = k

    3      

Equation at the end of step  3  :

 k -  2  = 0

Step  4  :

Equation at the end of step  4  :

 k - 2  = 0

Step  5  :

Solving a Single Variable Equation :

  Solve  :    k-2 = 0

Add  2  to both sides of the equation :

                     k = 2

One solution was found :

                  k = 2

Step-by-step explanation:

Consider x⅓ =a

then the following expression can be written as

a²+a-2

a²+2a-a-2

a(a+2)-1(a+2)

(a+2)(a-1)

a= -2 or, a= 1

Putting the value of a

x⅓ = -2 and, x⅓ =1

What is the value of b?
tresset_1 [31]

Answer:

17

Step-by-step explanation:

Using the law of cosines in ΔABC

b² = a² + c² - (2ac cosB) ← substitute in values

   = 25² + 28² - (2 × 25 × 28 × cos36.9°)

   = 625 + 784 - 1400 cos36.9°

   = 1409 - 1400 cos36.9° ( Take the square root of both sides )

b = \sqrt{1409-1400cos36.9} ≈ 17 ( nearest whole number )

The area of a square is 49 square meters. How long is each side?
Artemon [7]

A square has 4 equal sides, which means when you need to work out the area, you're doing length × width, but the length and width are exactly the same, because it's a square (look at the picture if you don't understand this).

That means you just have to pick any side (let's call this side x), and multiply it by another side of the square. Now, because all of the sides are equal, you're doing x multiplied by x, which is the same as x².

Therefore, if the area is equal to x², and in this question, it's also equal to 49 (as stated in the question), we can equate them to each other:

x² = 49

Now to get the x by itself, we need to do the opposite of squaring, which is square rooting. Therefore, we square root both sides of the equation:

√x² = √49

The √ and the ² cancel out, so you're just left with x:

x = √49

The square root of 49 is just 7, so we can replace √49 with 7, and we get:

x = 7

Now remember, earlier, I called x the value of one side. Therefore, by remembering that, you know that the value of one side is equal to 7. And because all the sides are the same as each other, each side is equal to 7 metres.

Therefore, your final answer is 7 metres :)
