Answer:
The answer is letter A.
Step-by-step explanation:
y=mx+b
-3=(-1)(0)+b
-3=0+b
0 0
-3=b
y= -1x-3
A^2=B^2+c^2
8^2+15^2=X^2
so 289=X^2
the square root or 289 is 17, so the answer is 17ft
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.
