I got the same answer as you. Try to ask your teacher about it since it’s a math problem online or something.
You just have to answer to all of the questions and bullet points. Think about them, and do some sketches. In the end that will help you to end the assignment.
Hope it helped.
Answer:
<u><em>4 boxes of tiles.</em></u>
Step-by-step explanation:
Both rooms are square, so each has equal sides. Let's set a side to room A as x. It's area would be x^2. Room B has sides = 2x, so it's area would be (2x)^2 or 4x^2. The ratio of the areas B/A = 4x^2/x^2. B/A = 4.
Room B has 4 times the area of A. If one box of tile completes Room A, Room B would need four times that amount, or 4 boxes.
y=2x+4
that is an equation in slope intercept form where the slope is 2 so you would go up two right 1 and the y intercept would be 4 so (0,4)
