Lance wants to find the total length of three boards. he uses the expression 3 1/2+2+4 1/2 how can lance rewrite the expression using both the associative and community properties of addition

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

r = 78539458390583095803458309458039485093485 or just 3
