A regular octagon has a perimeter of (32x+56) units. What is the length of one of its sides, in units?

Which expression shows the result of applying the distributive property to -2(1/3x - 1/5) right answer pls.. 2/3x + 2/5 -2/3x - 2/5 2/3x - 2/5 -2/3x + 2/5

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Solve for n? [tex]z = \frac{3}{4} mn[/tex]
