Answer:
j = 4 and k = 10
Step-by-step explanation:
D
8x³ - 125 is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²)
here 8x³ = (2x)³ ⇒ a = 2x and 125 = 5³ ⇒ b = 5
8x³ - 125 = (2x - 5)((2x)² + (2x × 5) + 5²) = (2x - 5)(4x² + 10x + 25 )
compare the coefficients of like terms with jx² + kx + 25
jx² = 4x² ⇒ j = 4 and kx = 10x ⇒ k = 10 → D

(4, -6)
(x1+x2)/2 + (y1+y2)/2 = midpoint
(11+-3)/2 = 8/2 = 4. x = 4
(-5 + -7)/2 = -12/2. y = -6
4, -6 is the midpoint
