V * v = v^2
v * -8 = -8v
8 * v = 8v
8 * -8 = -64
v^2 - 8v + 8v - 64
v^2 - 64

This was using the distributive property or using the FOIL method</span>
all real numbers is the domain of the function y=x+4
the formula for the Pythagorean theorem is a squared plus b squared is equals to c squared we don't have our a so it will be 8 * 8 =64which is 64 is equals to 10 * 10 which is 100 - 64 is equals to 36 then you square root do square roots the 36 which is 6
You need the percentages to answer the question
The answer is 690 if you subtract the two numbers you will find the cost of the bench.
