-2v3 + v75
Lena [83]

Answer:

a)      3\sqrt{3}

Step-by-step explanation:

Step(i):-

Given     - 2 √3 + √75

     we know that        25 × 3 = 75

                 - 2 √3 + √75    

            =    -2 √3 + \sqrt{25 X 3}

By using

       \sqrt{ab} = \sqrt{a}  \sqrt{b}

          =  -2\sqrt{3} + \sqrt{25} X \sqrt{3}

         =  -2\sqrt{3} + 5  \sqrt{3}

        = (-2 + 5 ) \sqrt{3}

       = 3\sqrt{3}

Solve both equations and pls show work.. <br> I will mark brainliest
Alexxx [7]

Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

1/4(1-2/3)^2+1/3 Simplify
MrMuchimi

Simplifying the expression gives 13/ 36

<h3>How to solve the expression</h3>

Given;

1/4(1-2/3)^2+1/3

Represented as;

\frac{1}{4} * ( 1  - \frac{2}3} )^2 + \frac{1}{3}

Take the LCM of the bracket

\frac{1}{4} * ( \frac{1}{3} )^2 + \frac{1}{3}

Find the square

\frac{1}{4} (\frac{1}{9} )+ \frac{1}{3}

Find the LCM

\frac{1}{36} + \frac{1}{3}

1 + 12/36

13/ 36

Thus, simplifying the expression gives 13/ 36
