Answers & Comments
Answer:
1. The perimeter of the rectangle is 2x² + 16x - 10.
2. To find the perimeter of the rectangle, we need to add up the lengths of all four sides. In this case, we have:
Perimeter = 2(length + width)
Substituting the given expressions for the length and width, we get:
Perimeter = 2((3x-1) + (x²+5x-4))
Simplifying the expression inside the parentheses, we get:
Perimeter = 2(x² + 8x - 5)
Expanding and simplifying, we get:
Perimeter = 2x² + 16x - 10
Therefore, the perimeter of the rectangle is 2x² + 16x - 10.
3. In solving the problem, the first thing to consider is to identify what is being asked and what information is given. In this case, we are asked to find the perimeter of a rectangle, which requires adding up the lengths of all four sides. We are given expressions for the length and width of the rectangle, which can be used to calculate the perimeter. It is also important to simplify the expression to get the final answer.
Step-by-step explanation:
Based on the problem presented, we are given the dimensions of a rectangle - the width is 3x-1 and the length is x²+5x-4, and we are asked to find the perimeter of the rectangle.
To find the perimeter of the rectangle, we need to add up the lengths of all four sides. In this case, we have:
Perimeter = 2(length + width)
Substituting the given expressions for the length and width, we get:
Perimeter = 2((3x-1) + (x²+5x-4))
Simplifying the expression inside the parentheses, we get:
Perimeter = 2(x² + 8x - 5)
Expanding and simplifying, we get:
Perimeter = 2x² + 16x - 10
Therefore, the perimeter of the rectangle is 2x² + 16x - 10.
