" if for a polynomial with rational coefficients has irrational roots then these irrational roots will always appear in pair " .
we are given that
and
are two roots of a polynomial equation with rational coefficients, then it's complex conjugate is also a root of this polynomial equation i.e. '
' and '
' are also roots of this polynomial equation.

Answer: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%

Answer:
the volume of this can only be solve as pedmas or diver prop
Step-by-step explanation:
the two x and four x with 3x+3x+6
Equate P as 62.10 since we are looking for the MAX value for x (then a legitimate one if necessary)
(20 + 0.5x) + (3 + 0.075x) = 62.1
= 0.575x + 23 = 62.1
x = (62.1-23)/0.575
x = 680
Answer:
189
Step-by-step explanation:
