Answer: the bottom right one
Step-by-step explanation:
you can put your pencil like this I and follow the line without two parts touching the line (vertical line test)
No, because the sum of the angles of any polygon is equal to 180(n-2), where n is the numbers of its sides, and 450÷180=2.5
Hope this helped!
Answer:
The area of the patio without the tub is 53.44 ft²
Step-by-step explanation:
In order to calculate the area of the patio that is not covered by the hot tub we need to calculate the total area of the patio and subtract it by the area of the tub. Since the patio is rectangular it's area is given by "area = length*width" and the area of the tub is given by "area = pi*r²".
area patio = length*width = 11*6 = 66 ft²
area tub = pi*r² = pi*(48/2)² = pi*(24)² = 1,808.64 in²
To compare the area we need to convert the areas to the same unit, to do that we will convert the area of the tub from in² to ft², in order to do that we need to divide the value by 144. We have:
area tub = 1,808.64/144 = 12.56 ft²
The area of the patio without the tub is:
x = area patio - area tub = 66 - 12.56 = 53.44 ft²
We just need to complete the square for the x terms
gropu x terms
x^2-4x
take 1/2 of linear coefient and square it
-4/2=-2, (-2)^2=4
x^2-4x+4
factor
(x-2)^2
h=2
