The value of c is 
Explanation:
Given that the trinomial is 
We need to determine the value of c such that the trinomial is a perfect square.
The value of c can be determined using the formula,

From the trinomial, the value of b is given by

Substituting the value of b in the above formula, we have,

Squaring both the numerator and denominator, we have,

Thus, the value of c is
which makes the trinomial a perfect square.
So multiply with powers is actually adding powers with same base
So answer is 12a^(2+3)b^(2+1) = 12a^5b^3
Answer: D= csc theta
Step-by-step explanation:
10 - p.
Nicholas would have spent $p, so he has $p less than $10!
