Which expression is equivalent to (8.4x+2.9)+(−3.7x+5)? Will give brainliest for the best answer & explanation!

A
−4.7x+7.9

B
4.7x+7.9

C
−12.1x+7.9

D
12.1x+7.9

Step-by-step explanation:

so we know that

(8.4x+2.9)+(−3.7x+5)= 4.7x+7.9

so we need an equivelant to 4.7x+7.9

A. −4.7x+7.9= -1/10x(47x-79)

B.=4.7x+7.9=1/10x(47x+79)

C.−12.1x+7.9=-1/10x(121x-79)

D.12.1x+7.9=1/10x(121x+79)

So the answer would be B!
