In technical fields like carpentry or structural engineering, precise calculations often involve working with irrational numbers. Match each part of the simplification process for the expression $(4 + 5\sqrt{7})(4 - 5\sqrt{7})$ with its corresponding value or pattern.

In a precision manufacturing workshop, a technician is required to simplify the expression $({}4 + 5\sqrt{7})({}4 - 5\sqrt{7})$ to calculate a material's tolerance level. According to the product of conjugates pattern, $(a + b)(a - b) = a^2 - b^2$, which of the following represents the correct initial setup for this simplification?

In a precision metalworking shop, a technician needs to simplify the expression $({}4 + 5\sqrt{7})({}4 - 5\sqrt{7})$ to calculate the offset for a machine part. Arrange the following steps in the correct order to simplify this expression using the Product of Conjugates Pattern.

In a precision metalworking shop, a technician evaluates the expression $(4 + 5\sqrt{7})(4 - 5\sqrt{7})$ to determine the clearance for a custom component. True or False: Using the Product of Conjugates Pattern, $(a+b)(a-b) = a^2 - b^2$, this expression simplifies to the final integer value -159.

A quality control technician is evaluating the thermal expansion of a machined part and needs to simplify the expression $({}4 + 5\sqrt{7})({}4 - 5\sqrt{7})$ to find the differential coefficient. Recalling the Product of Conjugates pattern, $(a+b)(a-b) = a^2 - b^2$, the technician evaluates the square of the first term as 16 and the square of the second term as 175. The final simplified integer value for the coefficient is ____.
