First step of the equation is to simplify the equation 2a • b = a2 + b2 into 2 ab = a2 + b2. This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9. hence the answer to this problem is false. we can try another values to verify.
Answer:
The circumference of the horse pin is 150.86 feet
Step-by-step explanation:
In this question, we are to calculate the circumference of the horse pin, given that the diameter is 48 feet.
Mathematically, the circumference can be calculated using the formula
C = 2 * pi * r
where r = D/2 = 48/2 = 24 feet
The circumference C is thus = 2 * 22/7 * 24 = 1056/7 = 150.86 feet

"In Grade 2 and early in Grade 3, students learned to use bar models to solve two-step problems involving addition and subtraction. This is extended in this chapter to include multiplication and division.
<span>Both multiplication and division are based on the concept of equal groups, or the part-part-whole concept, where each equal group is one part of the whole. In Grade 2, students showed this with one long bar (the whole) divided up into equal-sized parts, or units. This unitary bar model represents situations such as basket of apples being grouped equally into bags." </span>https://www.sophia.org/tutorials/math-in-focus-chapter-9-bar-modeling-with-multipli
