4√7+(2/√7+1/√5)·√35-(1/√125-1/√175) ·25√35-7√5=

Sir is this high school math or something like that because I never seen this in middle school

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

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
