Answer:
Step-by-step explanation:
Substitute with x and y with 3:-
First, Multiply -1 and 3 = -3
Subtract 7 from -3 = -10
Multiply 2 and -10 = -20

The length and width of rectangle Z would be 4 inches as the width and 4 inches as the length. This is because first, you combine and find the total perimeter of Rectangle Y. The perimeter of rectangle y would be P=length + length + width + width, which is 16 inches. Rectangle Z has the same perimeter total as rectangle Y and rectangle Zs area is the same as rectangle Y. 4x4 is equal to 16 while to find the perimeter, 4+4+4+4 is also 16.

The last one is your answer :))
Step-by-step explanation:
The equation of a circle is (x-h)^2 + (y-k)^2 = r^2. Where "x" and "y" are variables, "h" and "k" are the coordinates of the center of the circle, and "r" is the length of the radius. It is given that the center of the circle is (-27, 120). So, h= -27 and k= 120. If the circle passes through the origin, we can assume that the origin is on the circle. Since a circle's radius is constant no matter where it is drawn/is, we can find the radius of the circle by finding the distance between the circle's center (-27, 120) and the origin, (0, 0). The distance formula is: d= √((x[2]-x[1])^2-(y[2]-y[1])^2). If the coordinates of the center of the circle are (x[2}, y[2]), then x[2]= -27 and y[2]= 120. Then, the origin is the (x[1], y[1]). So, x[1] = 0 and y[1] = 0. Plugging the numbers in we get: √((-27-0)^2-(120-0)^2). This gives us √(729+14400) = 123. So since the distance between the center of the circle and a point on the circle is 123 (units), then the radius has a value of 123.
Plugging all the numbers into the equation of a circle, we get: (x-(-27))^2+(y-120)^2=123^2.
