Answer:
Step-by-step explanation:
y = total cost and x = number of tons
y = 125x + 7500
the total cost for transporting 15 tons...sub in 15 for x
y = 125(15) + 7500
y = 1875 + 7500
y = $ 9375 <===== total cost

The complete question is
"Point P is the incenter of triangle ABC, PZ = 7 units, and PA = 12 units.
The radius of the incircle centered at point P is ? units."
The radius of the incircle centered at point P is 7 units.
We are given that point P is the incenter of the triangle, and is the center point of the incircle of the triangle.
<h3>What is incircle?</h3>
The incircle is defined as the largest circle that can be made in a triangle and is tangent to each side of the triangle.
Here, The radius of the circle is going to be a perpendicular line from point P to any side of the triangle.
In the triangle ,
PZ = PY = PX,
Each measure of value is equal to the radius of the circle.
Therefore, we already know that PZ = 7 units making the radius, r = 7 units.

Answer:
The solution is in the attached file
For the answer to the question above, I'll show you the step by step.
6/a^2-7a+6, 3/a^2-36
<span>= 6 / (a²-7a+6) + 3 / (a² - 36) ← (uses) </span>
<span>multiplying the Denominator → (a²-7a+6)(a² - 36) ← LCD </span>
<span>= 6(a² - 36) / (a²-7a+6)(a² - 36) + 3(a²-7a+6) / (a²-7a+6)(a² - 36) </span>
<span>= [6(a² - 36) + 3(a²-7a+6)] / (a²-7a+6)(a² - 36) </span>
<span>= [6a² - 216 + 3a² - 21a +18)] / (a²-7a+6)(a² - 36)
</span>The answer is
<span>= [9a² - 21a - 198] / (a²-7a+6)(a² - 36)
