Which equation has the solution, n=1.1 ? Answer Choices 3n+5=1.7 4n+6=1.6 3.3n−6.7n=11 3n+1.7=5
1 answer:
The last one, because when you have to solve an equation, first you have to rearrange the equation, so that all the n’s are on one side of the equation and the numbers are on the other. Then, you just divide both sides by the number multiplying n to find the value of just one n. I hope this helped! I even included another example question that explains it a bit better.

Answer:
Option (A) and (C).
Step-by-step explanation:
Prime polynomial can't be written as a product of lower degree polynomials.
(A)
=8x²-6x-4x-3
=2x(4x-3)-1(4x+3)
Here we can't write the polynomial as a product of lower degree.
Therefore it is a prime polynomial.
(B)
8x²+2x-3
=8x²+6x-4x-3
=2x(4x+3)-1(4x+3)
=(4x+3)(2x-1)
Therefore it is not a prime polynomial.
(C)
8x²-6x-3
Therefore it is a prime polynomial.
(D)
8x²+23x-3
=8x²+24x-x-3
=8x(x+3)-1(x+3)
=(x+3)(8x-1)
Therefore it is not a prime polynomial.
