N= 18
5/6=15/n you cross multiply them and you get 5n=90
Then you get the n by itself by doing 5n/5 and then you do the same to the other side by doing 90/5 and you get n=18
675/1000 = 0.675 L (Answer)
In 675 mL x 1L/1000 mL = 0.675 L
The sum of two numbers
6x6=36
Twice first number
6x2=12
Minus the second
12-6=6
ANSWER
First number=6 Second number=6
Basically you’re multiplying them both
(x^3 + 2x - 1)(x^4 - x^3 + 3)
so you need to make sure you multiply each one, if you do it right, you should end up with
x^7 - x^6 + 3x^3 + 2x^5 - 2x^4 + 6x -x^4 +x^3 -3
simplify by adding like terms
x^7 - x^6 + 2x^5 - 3x^4 + 4x^3 + 6x - 3
your answer would be the third option
