Consider two polynomial functions P1(x) and P2(x). Since the polynomials are closed under subtraction, the difference P1(x) − P2(x) must be Select one:
A. a polynomial function
B. an exponential function
C. a linear function

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
