3+2 root 2/ 2- root 2 = a+b root 2please answer

Answer»

ANSWER:

a=5

B=3.5 or 7/2

Step-by-step explanation:

(3+2 √2)/( 2- √ 2) = a+b √ 2

LHS=(3+2 √2)( 2+ √ 2)/( 2- √ 2)( 2+√ 2)

     = (6 + 3 √2 + 4√2 + 4 ) / ( 4- 2)

     = (10 + 7√2)/2

    = 5 + 7√2/2

    = RHS  =   a+b √ 2

THEREFORE

a = 5 and b= 7/2 (answer )

What single decimal multiplier would you use to decrease by 2% followed by a 7% decrease?

Answer»

Step-by-step explanation:

GIVEN: First decrease = 7%

Second decrease = 20%

To find: A single decimal MULTIPLIER

Solution:

To increase by 7% FOLLOWED by 20%, the single decimal multiplier will be -

= 27 + 7/5

= 135 + 7/5

= 142/5

Multiply 2 * 6

3x = 12

Solving

3x = 12

Solving for variable 'x'.

Move all terms CONTAINING x to the left, all other terms to the right.

Divide each side by '3'.

x = 4
