Determine the percentage of the shaded cubes
First, we calculate the number of boxes:

Express as multiplication


This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:





<em>30% were shaded</em>
Answer:
c = 
Step-by-step explanation:
Given
R= 
Clear the radical by squaring both sides
R² = b² - 4ac ( subtract b² from both sides )
R² - b² = - 4ac ( multiply all terms by - 1 )
b² - R² = 4ac ( divide both sides by 4a )
= c
Answer:
b. (x-3)(x+2)
Step-by-step explanation:
y=x^2-x-6
y=x^2-3x+2x-6
=x(x-3)+2(x-3)
=(x-3)(x+2)
First simplify
-8+9w-23
Then Group simliar terms
(-8-23)+9w
After simplify
-31 +9w
