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>
Y= 5 y =7 thats the smaller slip and larger
Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side
Answer:
false
Step-by-step explanation:
because
-3(x-5)
-3x+15
