Answer: I don't think any of those choices are correct.
Step-by-step explanation:
2-6*-5t+6
6*-5t+4
<h3>-30t+4</h3>
So 29-4 =25... which is a perfect square
Answer= +/- 5
The sum of b and f is b+f
Three times this sum is 3(b+f)
is the polynomial of one variable with second-order and
is the polynomial of two variables with third-order
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have polynomials:
and

For 
In this polynomial, the number of variables is one and the maximum power of x is 2, therefore:
This is the polynomial of one variable with second order.
In polynomial,
there are two variables x and y.
The maximum power of x is 3( x has a power of 2 and y has a power of 1)
This is the polynomial of two variables with third order.
Thus,
is the polynomial of one variable with second-order and
is the polynomial of two variables with third-order.
