Final answer:
To calculate the perimeter of the rectangle, use the formula P = 2l + 2w, resulting in P = 4x + 8.
Step-by-step explanation:
The question seems to ask about finding the perimeter of a rectangle with sides measuring 2x-3 and 7. To find the perimeter of a rectangle, you add up the lengths of all four sides.
Since a rectangle has two pairs of equal sides, the formula is P = 2l + 2w where P is the perimeter, l is the length, and w is the width. So, the perimeter would be P = 2(2x-3) + 2(7), which simplifies to P = 4x - 6 + 14, or P = 4x + 8.
The question asks for the perimeter of the expression 2x-3 and 7. To find the perimeter, we add up all the sides of the shape. In this case, the expression 2x-3 and 7 represents a straight line, and the perimeter of a line is the distance between its endpoints.
To find the distance between two points, we can use the distance formula: sqrt((x2-x1)^2 + (y2-y1)^2). Since we are given two points (0, 2x-3) and (7, 7), we can substitute the values into the distance formula to find the perimeter.
