Answer:
27.73 square centimeters
Step-by-step explanation:
<em>Assume the shaded region is the area outside the circle but inside the rectangle.</em>
<em />
Now, we need to find the area of rectangle and area of circle. Then we will subtract area of circle from area of rectangle to get our desired answer.
Area of Rectangle = length * width
Area of Rectangle = 8 * 7 = 56
Area of circle is given by the formula:
Area = 
Where r is the radius, which is 3
So,
Area of Circle = 
Thus, area of the shaded region is:
Area of Shaded Region = 56 - 28.27 = 27.73 square centimeters
Answer:
Step-by-step explanation:
Assuming that the patio is a rectangle, we have
Where 
is the length and 
is the width.
Now let's assume that the length of the patio is double than the width.
So, the equation that represents this problem is
Answer:
Uhh? You can't factor this!
Step-by-step explanation:
So.. we see that the last term, the constant, (the +5) is positive, which means the two terms (the a and b on the (x+a)(x+b) must be either both positive or both negative).
We try positive, and we end up with
(x+1)(x+5)
x^2 + x + 5x + 5
x^2 + 6x + 5
which is not what we want!
We try negative, and we end up with
(x-1)(x-5)
x^2 -x -5x +5
x^2 -6x +5
which is also not what we want!
This isn't factorable!
You can always complete the square or utilize the quadratic equation, but you can't factor it.
if your asking for the equation, it's t + 7 < 3
Step-by-step explanation:
- 16-19 -> 3 (16, 17, 19)
- 20-23 -> 1 (21)
- 24-27 -> 3 (24, 26, 26)
- 28-31 -> 4 (28, 29, 30, 31)
- 32-35 -> 5 (32, 33, 34, 34, 35)
