$\large \boxed{\sf \ \ \sum_{n=1}^{n=4} (5n + 2) = 58 \ \ }$

Step-by-step explanation:

Hello,

We need to compute the following:

$\displaystyle \sum_{k=1}^{k=4} (5\cdot k + 2)= (5*1+2) + (5*2+2)+ (5*3+2) + (5*4+2)\\\\=7 + 12 + 17 + 22 = 19 + 39 = 58$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

(-3,6)

Step-by-step explanation:

We know that the standard equation a circle is given by ":-

(x-h)^2+(y-k)^2=r^2 , where r is the center of the circle and (h,k) is the center of the circle.

The given equation of the circle : (x +3)^2+ (y - 6)^2 = 24

which is equivalent to (x -(-3))^2 + (y - 6)^2 = 24

It implies the coordinates of the center of the given circle =(-3,6)
