Step-by-step explanation:

Evaluate=

(256 x 3^-5 x 6)^-2 x (3^2/2^3)^4 x 2^28

(256 x 1/243 x 6)^-2 x (3^2/2^3)^4 x 2^28

(256 x 1/243 x 1)^-2 x (3^2/2^3)^4 x 2^28

Multiply=

(256/243)^-2 x (3^2/2^3)^4 x 2^28

Evaluate=

59049/65536 (3^2/2^3)^4 x 2^28

59049/65536 (1/9/2^3)^4 x 2^28

59049/65536 (1/9/8)^4 x 2^28

Divide=

59049/65536 (1/72)^4 x 2^28

Evaluate=

59049/65536 x 1/26873856 x 2^28

Let A = {x : 2x² + 3x - 2 = 0} and B = {x : x² + 3x - 4 = 0 } find (A U B) × (A Π B)

ivann1987 [24]

Given :

A = {x: 2x² + 3x - 2 = 0 }
B = {x : x² + 3x - 4 = 0 }

To find :

(A U B ) × (A Π B )

Solution :-

The first set is ,

A ={x : 2x² + 3x - 2 = 0}

Solving the Quadratic equation ,

2x² + 3x - 2 = 0
2x² + 4x - x - 2 = 0
2x( x + 2) -1( x + 2 ) = 0
(2x -1) ( x + 2) = 0
x = 0.5 , -2

Hence ,

A ={0.5, -2}

The second set is ,

B ={ x :x² + 3x - 4 = 0 }

Solving the Quadratic equation ,

x² + 3x - 4 = 0
x² + 4x - x - 4 = 0
x( x + 4)-1 ( x +4) = 0
(x + 4) ( x -1) = 0
x = 1 , -4

Hence ,

B ={1,4}

Now ,

A U B = { 0.5 , 1 , 4 , -2}
A Π B = {∅ }

Since AΠ B is a null set , hence ,

A × B = {∅}

HELP PLS Solve for x x=[?] 3x + 2 6x - 20

Sloan [31]

Step-by-step explanation:

Remember that the sum of angles on a straight line are supplementary. (180°)

Therefore 3x + 2 + 6x - 20 = 180.

=> 9x - 18 = 180

=> 9x = 198

=> x = 22.

Does 24, 7, and 26 form a right triangle

const2013 [10]

Answer:

No. It is an obtuse triangle.

Step-by-step explanation:

If c^2>a^2+b^2, then the triangle is obtuse. Since 24^2 + 7^2 is 625, and the square root of 625 is 25, that means 26>25. This proves that the triangle is obtuse.
