There are six clearly distinguishable frogs sitting in a row. Two are green, three are red, and one is blue. Green frogs refuse to sit next to the red frogs, for they are highly poisonous. In how many ways can the frogs be arranged?

i believe it is 18

Step-by-step explanation:

green1 green2 blue red1 red2 red3

green2 green1 blue red1 red2 red3

green1 green2 blue red2 red1 red3

green2 green1 blue red2 red1 red3

green1 green2 blue red3 red2 red1

green2 green1 blue red3 red2 red1

green1 green2 blue red1 red3 red2

green2 green1 blue red1 red3 red2

red1 red2 red3 blue green1 green 2 everthing above but this way

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

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.
