Answer:
Area of red band is 
Step-by-step explanation:
We know that area of square = 
Please refer to the attached figure, we have to calculate the area of red band.
Required area = Area of square <em>ABCD </em>- Area of <em>purple square
</em>
Side of purple square = 
So, area of purple square = 
<em>ABCD </em>is a square with purple square at the center and there is symmetry in the figure.
So, width of red band towards both the end is 5 inches.
Required area = 
Using formula 
Hence, Area of red band is
Answer:
Okay so for this you will use the FOIL (first, outer, inner, last) method.
Step-by-step explanation:
So, first you take the x from (x-3) and multiply it by the x in (x-4).
So, now you have x^2
Then you do the outer which would be x multiplied by 4.
Now you have -4x.
Then you multiply the inner which is -3 times x.
Which is -3x.
Now its the last which is -3 times -4 which equals 12.
Now you put them in order:
x^2 - 4x - 3x + 12
Lastly, you combine like terms:
x^2 -1 + 12
Answer:
.
10% of 50 coins is/are 5 coins. So, 5 coins are pennies.
40% of 50 coins is/are 20 coins. So, 20 coins are dimes.
The number of nickels is (5 + 9) = 14, according to the condition.
Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.
Now you can easily calculate the total and answer the question
Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50. ANSWER
