Answer:

Step-by-step explanation:

hello :

x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0

(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40

german

Answer:

x = (13) ^ 1/3

x is approximately 2.351334688

Step-by-step explanation:

x^3 + 7 = 20

Subtract 7 from each side

x^3 + 7-7 = 20-7

x^3 = 13

Take the cube root of each side

x^3 ^ 1/3  = (13) ^ 1/3

x = (13) ^ 1/3

x is approximately 2.351334688

1/3m=12-m SOMBODY PLEASE HEELP
denis23 [38]
Let's solve your equation step-by-step.
1/3m=12−m
Step 1: Simplify both sides of the equation.
1/3m=12−m
Simplify: (Show steps)
1/3m=−m+12
Step 2: Add m to both sides.
1/3m+m=−m+12+m
4/3m=12
Step 3: Multiply both sides by 3/4.
(3/4)*(4/3m)=(3/4)*(1/2)
m=9
Answer: m=9
