Replace x with -2 in the equation and solve.
3(-2) +1 = -6 + 1 = -5
Probability of first red = 1/5
and Probabiliiy of the green =1/5 the red again is 1/5.
Required probability is (1/5)^3 = 1/125
its D
The answer is x

Answer:
420
Step-by-step explanation:
The number of students in the school is unknown, so we'll call it x.
55% of the number of students are girls.
There are 321 girls.
55% of x = 231
0.55x = 231
x = 231/0.55
x = 420
Answer: 420
Y=102 X=78
There is 900 degrees in a hexagon so you have to add up all the sides you already know and subtract 900 minus all the degrees you added then when you get your answer you can see that there is a supplementary line connecting to the hexagon and we know that a line is 180 degrees so you then subtract 180 with the degree you just found:)
