To start, you can use clue 2 because there is only one variable in it.
Solve for the value of the circle, by dividing both sides by 3.
Then you can plug that value into clue 1 to solve for the diamond.
Once you find the value for the diamond, you can plug both values, the diamond and the circle, into clue 3, to solve for the triangle.

Answer:
6 2/3 cups needed
Step-by-step explanation:
So first I would find the unit rate for cookies and cups
1 cup = 9 cookies
So now divide becuase we want to find the amount of cookies
60/9= 6.666666666 or 6 2/3
Now normally it would just be left like that
Answer: The area of yellow band is sq. inches.
Step-by-step explanation:
Let the side length of the red square be 'x' inches
Width of the yellow band surrounds the red square = 6 inches
So, Length of band would be
Width of band would be
So, Area of the yellow band would be
Hence, the area of yellow band is sq. inches.
-3 = x^2 + 4x + 1
0 = x^2 + 4x + 1 + 3
0 = x^2 + 4x + 4
Discriminant is b^2 - 4ac.
4^2 - 4(1)(4)
16 - 4(4)
16 - 16 = 0
Discriminant Rules:
1. If b²-4ac is negative, there are no real answers.
2. If b²-4ac is zero, there is one real answer.
3. If b²-4ac is positive, there are two real answers.
Based on rule 2, the answer is ONE REAL ROOT.
