I believe it’s 13
you would substitute the x for 3
so you would multiply 4 by 3 and get 12
you then would add 1
Polynomial is an expression of more than two algebraic terms.

Definition of quadrilateral:</h3>
- A quadrilateral is a four-sided polygon with four edges (sides) and four corners in geometry (vertices).
- The name comes from the Latin words quadri, which means "four," and latus, which means "side."
- In comparison to other polygons, it is also known as a tetragon, derived from the Greek "tetra" meaning "four" and "gon" meaning "corner" or "angle"
- In the same way as other polygons (e.g. pentagon). While "gon" means "angle," it's also known as a quadrangle or 4-angle.

Answer: Option 'A' is correct.
Step-by-step explanation :
Since we have given that
Number of medals = 2
Number of runners = 8
We need to find the number of ways to award the medals.
We would use "fundamental theorem of counting" to find the number of ways.
So, number of ways is given by
8 × 7 = 56
Hence, option 'A' is correct.
You are right: the graph does not represent a proportion, because it does not go thru the origin.
We define the variables:
p: cost of bushel of peaches
w: cost of watermelon
We wrote the system of equations:
12p + 5w = 150
15p + 8w = 198
We can represent the system in matrix form as
Ax = b
Where,
A = [12 5; 15 8]
b = [150; 198]
x = [p; w]
