You're just a step away from the equation of the line that's perpendicular to [ y = 5/6 x + 7 ]. ... You know that its slope is -6/5 and that it contains the point (3, 2). ... Find the equation of that line. Then find the point where the two lines intersect. Then find the distance between that point and (3, 2). SIR !
Answer: 6400<em>x²</em> · (<em>x - 1)²</em>
The rule says: To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (x-1) and the exponents are:
1, as (x-1) is the same number as (x-1)1
And 1, as (x-1) is the same number as (x-1)1
The product is therefore, (x-1) (1 + 1) = (x-1)²
It is triangle ACK by the rule of AAS.

I am thinking your answer is 78 students. You do 1/5 times 390. And I think the the part about the dog is just extra information.
