Answer:
∴(x+5)(x+3) =x²+8x+15
Step-by-step explanation:
Standard form of a polynomial:
Standard of polynomial means that the terms ordered from biggest exponent of variable to lowest exponent of variable.
Example:

Given,
(x+5)(x+3)
=x(x+3)+5(x+3)
=x²+3x+5x+15
=x²+8x+15
∴(x+5)(x+3) =x²+8x+15
The degree of the polynomial is 2 and is a one variable polynomial.
Answer:
n = 18
Step-by-step explanation:
18/27 = 12/n
18 * n = 12 * 27
18n = 324
n = 324/18
n = 18
Answer:
option B
Step-by-step explanation:
Rule:output=input -2
