sergejj [24]

You must find the factors of each number...
9 = 1, 3, 3, 9
6 = 1, 2, 3, 6

Next, determine the common multiple...
9 = 1, 3, 3, 9
6 = 1, 2, 3, 6

Therefore, the most groups Lavinia can make without any glasses or mugs left to spare is 3.

Write the equation of a circle with a center at (-1,2) and a radius of 7

Sever21 [200]

Answer:

$(x+1)^2+(y-2)^2=49$

Step-by-step explanation:

The standard form for the equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where r is the radius, and the center is (h, k).

(h, k) = (-1, 2), r = 7

$(x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49$
