which pair of expressions is equivalent for any variable value greater than zero please answer by today.

3(x+2) and 3x+2
4d+2e and 8d+e
f+f+f+g and 3fg
b+b+3c and 2b+3c

Respuesta :

The last choice, b+b+3c and 2b+3c, is correct.

When adding like terms, you combine coefficients; for this expression, we have 1b+1b+3c = (1b+1b)+3c = 2b+3c
