If she lines the two ribbons up, end to end, the total lenght will be 17.021 cm.
Answer:
y=-3x-7
Step-by-step explanation:
Here's why we know that if a line is parallel to another they never cross so they must have the same slope. Then we plug in the values y=mx+b, y=-3x+b, then plug in x and y, -4=3+b, b=-7, therefore the equation is y=-3x-7
Give me an operation like the one you are talki ng about and I can solve it
volume of paper bag= 16×5×20=1600cmcube
volume of box= 8×3×10= 240
space left = 1600-240= 1360cmcube
hope it helps
