Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.
-- Remember this only works on perfect square polynomials.

Answer: Discounted function will be

Step-by-step explanation:
Since we have given that
Initial cost of solar energy = $9000
Average annual cost of heating a home with solar energy = $200
Rate of discount he received on the total cost = 25%
Let the number of year will be t
According to question, we need to write a discounted cost as a function of number of years.
So, our function becomes,

Hence, discounted function will be
