But can you help me on my question?
what is the area of the figure?
Answer:
<h3><u>Part (a)</u></h3>
From inspection of the diagram, the pattern is:
Step 1: 1² + 1
Step 2: 2² + 2
Step 3: 3² + 3
Let x = step number
Let y = total number of squares
Therefore, the equation that represents the relationship is:
y = x² + x
<h3><u>Part (b)</u></h3>
<u />
x² relates to the large square made up of small squares (top part of the image of each step)
x relates to the rectangle of small squares (bottom part of the image of each step)
y is the total number of small squares in the image of each step.
Answer: Your answer of the question is:
The scale factor is 0.8 or your first answer
Step-by-step explanation:
I know this because if you use the formula new over old or 8 over 10 in this case it is 8 is the pre-image and 10 is your image. So that is why the answer is 0.8 because its in the fraction of new over old is 8/10. I really hope I got it right and I hope you have a great weekend and a great school year. :)
