-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
