Step-by-step explanation:
we have

Distribute the number 2

Verify each case
case A) 3(b+2c)
distribute the number 3


therefore
Choice A is not equivalent to the given expression
case B) (b+3c)+(b+3c)
Combine like terms


therefore
Choice B is equivalent to the given expression
case C) 2(b)+2(3c)
Multiply both terns by 2

in this type of question , you just need to input the (x,y) , and see if the amount is correct
y - 0.75 = 1.25 (x-3)
2 - 0.75 = 1.25 ( 4 - 3)
1.25 = 1.25 (1)
1.25 = 1.25
hope this helps
