-4(2+8)=(-4×2)+(-4×n)

First you'd have to switch sides with the equation. After multiply what's inside the first two sets of parenthesis.

-4 ( 2 + 8 ) = ( -4 × 2 ) + ( -4 × n )

( -4 × 2 ) + ( -4 × n ) = -4 ( 2 + 8 )

-8 - 4n = -8 - 32

-8 - 4n = -40

After that you'd add 8 to both sides to make the equation simpler. Or in other words, to simplify. After you add -8 and 8, you should be left with -4n.

-8 + 8 - 4n = -40 + 8

-4n = -32

Finally, you need to divide both sides by -4 to get n on its own.

-4n = -32

\displaystyle\frac{-4n}{-4} = \frac{-32}{-4}

n = 8

The equation can no longer be simplified, so this is our final answer.

n = 8

-4(2+8) = (-4x2)+(-4xn)

-8-32 = (-8) + (-4n)

-40 = - 8 - 4n

-32 = -4n

8 = n

What is the radius of the circle ? (X-3^2+(y-4)^2=49
vodomira [7]

Answer:

7 units

Step-by-step explanation:

The formula for a circle is: (x-x_1)^2+(y-y_1)^2=r^2 , where (x_1, y_1) is the center of the circle and r is the radius.

Right now, we see that r^2 = 49, so to find r, we square root 49 and get 7.

Thus, the answer is 7 units.

Hope this helps!
