Final answer:
The coefficient of ? in the given equation is 4.
Step-by-step explanation:
The perimeter (length around) of a rectangle can be calculated by adding the lengths of all four sides. In this case, the side length is given as 2? + 2.0 1 and the width is given as 3 - 2. Let's substitute these values into the formula P = 2(length) + 2(width) to find the perimeter:
P = 2(2? + 2.0 1) + 2(3 - 2)
Simplifying the expression:
P = 4? + 4.0 2 + 6 - 4
P = 4? + 4 + 6 - 4
P = 4? + 6
Therefore, the coefficient of ? in P = 4? + 6 is 4.
