Therefore the total = 50 feet
Answer:
Substitute (x+4)2−16 ( x + 4 ) 2 - 16 for x2+8x x 2 + 8 x in the equation x2+y2+8x−6y=24 x 2 + y 2 + 8 x - 6 y = 24 . (x+4)2−16+y2−6y=24 ( x + 4 ) 2 - 16 + y 2 ...

Answer:
(x-4)(x-3)
Step-by-step explanation:
x²- 7x+12
=x²-4x-3x+12 applying midterm break
=x(x-4) -3(x-4)
=(x-4)(x-3)
