Given the formula for the perimeter of a rectangle where l represents the length and w represents the width. 2(l + w) what does the 2 represent in this formula? a) the 2 represents the perimeter. b) the 2 represents the two width pairs. c) the 2 represents the two length pairs. d) the 2 represents the two sets of length and width pairs.

For this one, I would go with D.

D makes the most sense, giving that there is two sets of each and, that it is just a shorter way to say "add all the sides."  

B and C would only give us half or part of the perimeter and then A does not make much sense.

D would be the answer through process of elimination.

answer: add the !

step-by-step explanation: then we will answer

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
