We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet, and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute <span>3*16 + 3*4 -20 equal to 40 feet.</span>
I believe the anwser to be 15 marbles
I hope this helps you
x^2-4x-12
x -6
x +4
(x-6)(x+4)
The answer is A. There is no multiplication sign in the problem. It’s all division.
