Which pair of expressions is equivalent for any variable value greater than zero?

D. b+b+3c and 2b+3c

Step-by-step explanation:

The question wants us to find out expressions is equivalent for any variable value greater than zero. So let's analyse all the possible answers to find the correct one.

A. (x+3) and 3x+ 2

If x = 1 , we have:

Both of the two sides are not equivalent

B. 4d+2e and 8d+e

If e=1 and d=1, we have:

Both of the two sides are not equivalent

C. f+f+f+g and 3fg

If f=1 and g=1, we have:

Both of the two sides are not equivalent

D. b+b+3c and 2b+3c

If b=1 and c=1, we have:

Both of the two sides are  equivalent

Or we will simplify the left side: b+b+3c = 2b+3c, hence 2b+3c = 2b+3c are apparent

So we choose D.

529 and 531

step-by-step explanation:

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
