Answer:

(x + 2)^2 + (y + 3)^2 = 9

Step-by-step explanation:

Center = (-2, - 3) = (h, k)

Radius (r) = 3

Equation of circle in centre radius form is given as:

(x - h) ^2 + (y - k) ^2 = r^2 \\\therefore \{x - (-2)\}^2 + \{y - (-3)\}^2 = 3^2 \\ \purple {\boxed {\bold {\therefore(x + 2)^2 + (y + 3)^2 = 9}}}

I need help ASAP! PLEASE!
Ulleksa [173]
First you would need to solve x.
2x+x+14+x-38=180
4x-24=180
4x=204
x=51
Now plug in the x for all three angle measures.
2(51)=102 degrees
51+14=65 degrees
51-38=13 degrees
Final answer is 102 degrees, 65 degrees, 13 degrees

2(3x - 4) = 2x + 12

6x - 8 = 2x + 12

4x = 20

x = 5

AB = 3(5) - 4 = 11

AC = 2(5) + 12 = 22

BC = 7(5) - 2 = 35 - 2 = 33

AC:BC = 22:33 = 2:3

Komok [63]

Answer: Amber use 30 feet of basic tiles and 6 feet of decorative tiles.


Step-by-step explanation:

Let x be the foot  of basic tiles and y be the foot of decorative tiles.

Now, according to the question, we have the following equations

x+y=36\\y=36-x\ .......(1)\\\\8x+20y=36\times10\\2x+5y=90.......(2)\ \ \ [\text{divide equation by 4}]

Put y=36-x in (2), we get

2x+5(36-x)=90\\\Rightarrow2x+180-5x=90\\\Rightarrow-3x=-90\\\Rightarrow\ x=30\\\\\Rightarrow\ y=36-30=6

Hence, Amber use 30 feet of basic tiles and 6 feet of decorative tiles.
