The model shows that may have planted flowers in her garden

So the question is asking find the area. Area is the total inside of a 2D shape. Hint:Length times width.So (10+5)*3. 10+5=15 then multiply 15 times 3 which is 45. She planted 45 flowers.

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
