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:

Hi!
A perfect square is the product of when a whole number is multiplied by itself
Ex:
6 × 6 = 36, 36 is the perfect square.
The number that is being multiplied is the square root.
So to find the correct answer for this question, let's use the process of elimination.
100 = 10 × 10 so we can cross out 100
64 = 8 × 8 so we can cross out 64
25 = 5 × 5 so we can cross out 25
Now all we have left is 24, which is not a perfect square.
Answer: A. 24

Answer:
they result in the same equation
Step-by-step explanation:
rewrite:
y = x + 9
y = x + 9
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x = −3/2
Decimal Form:
x = −1.5
Mixed Number Form:
x = −1/1/2
