Someone please do this problem for me.

Given:

To find:

The LCD of the fractions.

Solution:

LCD means least common denominator.

Let us find the least common multiplier for the denominator.

The denominators are .

Factor :

Take a common in first 2 terms and -6 common in next two terms.

Take out common factor (a - 1).

------------- (1)

Factor :

Using identity:

 ------------- (1)

From (1) and (2),

LCM of

Therefore LCD is (a - 1)(a - 6)(a + 6).

step-by-step explanation:

it's is b

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
