Answer:

Center (-5,4) radius 3

Step-by-step explanation:

The standard equation of a circle is

(x-h)^2+(y-k)^2=r^2

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

so h=-5 in this case and k is 4

r^2=9 so r=3

sdas [7]

Answer:

Step-by-step explanation:

Given number = -48

Listing out the possible factors of -48 in pairs along with their difference:

Factors ( $F_1\times F_2$ ) Difference ( $F1-F2$ ) Difference ( $F_2-F_1$ )

$-2\times 24$ -26 26

$2\times -24$ 26 -26

$-3\times 16$ -19 19

$3\times -16$ 19 -19

$-4\times 12$ -16 16

$4\times -12$ 16 -16

$6\times -8$ -14 14

$12\times -4$ 14 -14

On listing out the factors we find out that two of the pairs have difference = 19

The pairs are $-3, 16$ and $3,-16$

It is given that the factor with greater absolute value is positive. This means 16 would be positive while 3 would be negative.

So, our factors are $-3, 16$

The sum of the factors is = $-3+16=13$ (Answer)
