If the weight of a triangle is equal to 4 grams, and the weight of a square is equal to x grams. Which equation best represents this situation. A) 2x+1=3x+1
B) 2x+4=x+12
C) 3x=12x
D) x+4=x+4+4
PLEASE HELP

It’s letter B, the left part is the first part of the equation we see one triangle which is 4 and we 2 squares which equals to 2x, this gives us the first part which is 2x+4. The right part is the second part of the equation, we have 3 triangles which we have to multiply times 4 (4•3=12), we have one square which is equal to x, we put this together and we get x+12. Finally you put everything together to get the final answer which is 2x+4=x+12

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
