Answer with Step-by-step explanation:
The number of marbles are as under
3 red , 3 green , 1 Lavender total = 7
Now to select five marbles from a total of 7 marbles such that at least 2 marbles are included are the sum of the following cases:
1) We select 2 exactly 2 red marbles from 3 reds and the remaining 3 marbles are selected from 4 of other colours
Thus 
2)We select all the 3 red marbles and the remaining 2 are selected from the remaining 4 marbles

Thus the total number of ways are 
We can get rid of the parentheses so it looks like this:
3x + 24x + 8.
Simplify:
27x + 8
Answer:
3:1
Step-by-step explanation:
If you wrote this ratio out it would be 6:2. In order to find out the answer, simplify like a fraction 6/2 divided by 2 equals 3/1!
sorry if I am incorrect, but I hope this helped!
Answer:
<h3>Option 2 </h3>
angle 2 = 7x + 1 ( vertically opposite angles)
7x + 1 + 18x + 4 = 180° ( forming linear pair).
7x + 18x + 4 +1 = 180°
25x + 5 = 180°
25x = 180 - 5
25x = 175
x = 7°
angle 2 = 7(7)+ 1
= 50°
Step-by-step explanation:
(3⁸×3⁴)/(3²×3⁸)
3¹²/3¹⁰
3¹²-¹⁰
3².
