Answer 2

x represents one side, since there are 3 sides of a triangle, and 3*one side would give you the perimeter

Answer 7

Bethany wrote the equation mc011-1.jpg when she was told that the sum of three consecutive odd integers had a sum of 91. Which statement about her equation is true?
A.) Bethany is correct because consecutive odd integers will each have a difference of two.
B.) Bethany is correct because there are three xs in the equation and three is an odd number so it represents the sum of odd numbers.
C.) Bethany is incorrect because 2 and 4 are even numbers, she should use 1 and 3 in their place.
D.) Bethany is incorrect because consecutive integers always increase by 1 each time, not by 2

Answer 8

The equation is x+(x+2)+(x+4)=91
