Answer:

Answer:
9x-1
Step-by-step explanation:
The perimeter of the triangle is adding up all 3 sides.
(3x)+(x+6)+(5x-7)=P
9x-1 = perimeter
All I have done is combine like terms.
If there is a... x = something, replace x with the number.
True… irrational numbers focus more around square roots that cant be simplified into a single number, or symbols like pi. while not all rational numbers are whole, an irrational number can never be whole.
Area of a triangle: (b*h) /2
So :
(14,5 * 10.5) /2
=152,25 /2
= 76.125
