Bart and David are correct.
Bart
6x(1+2/3^3)
6x * 1 = 6x
6x *2/3^3 = 4x^3
6x * 4x^3

David
x(6+4x^2)
x*6 = 6x
x*4x^2 = 4x^3
6x+4x^3

Explain the different ways it is possible to add two rational numbers and get a negative number

snow_lady [41]

Answer:
both numbers are negative
negative number is greater than the positive number

Explanation:
In order to add two rational numbers and get a negative value, one of two scenarios should occur:
1- both numbers are negative.
In this case, the answer would definitely be negative as the two numbers are originally negative
Examples:
-9 + -2 = -9 - 2 = -11
$\frac{-1}{2} + \frac{-3}{2} = \frac{-4}{2} = -2$

2- negative number is greater than the positive number
In this case, the negative sign would dominate and the result would be negative
Examples:
-9 + 3 = -6
$\frac{-5}{6} + \frac{2}{6} = \frac{-3}{6}$

Hope this helps :)

(x+2)(x-18)=0 FIND THE SOLUTIONS OF THE EQUATION

vladimir2022 [97]

Either one at any given time could be equal to zero. So
x + 2 = 0
x = - 2

x - 18 = 0
x = 18

I've enclosed a graph of this so you can see that the answers I've given are the ones expected.
