X - age of Mikhail's
3x - age of Gabrielle (three times Mikhail's age)

x + 3x = 56
4x = 56 |:4
x = 14   <-- age Mikhail
3 * x = 14 * 3 = 42   <-- age Gabrielle

As is clear from the job three times the 14 to 42 by adding 14 gives 56, which is behind what they have in total.

G=3M

G+M=56

-------------------------------------------

3M+M=56

4M=56

M=56/4=14

---------------------------------------------

G+14=56

G=42

---------------------------------------------

So Gabriel is 42 and Mikhail is 14.

Answer:

-3 * (-4) matches, as well as the powers (I guess you wanted to communicate that these are powers, but it would also be correct if these where factors)

What is the center and radius of the circle?<br> (x-3)2 + y² = 4
Kipish [7]

Answer:

center = (3, 0)

radius = 2

Step-by-step explanation:

Standard equation of a circle:  \sf (x-h)^2+(y-k)^2=r^2

(where (h, k) is the center of the circle and r is the radius)

Given equation:

\sf (x-3)^2+y^2=4

Rewrite in standard form:

\sf \implies (x-3)^2+(y-0)^2=2^2

Therefore

  • center = (3, 0)
  • radius = 2
