What is the perimeter?
an isosceles triangle has a perimeter of 60 in. the congruent sides measure (2x+9)cm. The length of the third side is 3x cm. what is the value of x?
Again...sorry. = )
How do you think you should solve this problem?
I really have no idea. I am more confused with every question.
Are you sure that the perimeter is 60 inches?
2(2x + 9) + 3x = 60
Solve for x.
