Answer:
w 2 x 6
Step-by-step explanation:
Hello :
<span>note :
an equation of the
circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = <span>√20</span>
Answer:
Hi, I believe this is reflection then rotation. I haven't studied this in some time but from what I remember I think that would be the right answer. I hope I helped, have a nice day :)
X + (x + 2) + (x + 4) = 87
3x + 6 = 87
3x = 81
x = 27
The numbers are 27, 29, and 31
The area equation for a rectangle is length times width. And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.
So, you have to add the area of the rectangle and semi-circle together.
Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2
Add those together to get 307.17cm^2 or choice C.
