Answer:
(x-1)(x+1)(x+5)
Step-by-step explanation:
x^3+5x^2 - x-5=
x^3-x+5x^2-5=
x(x^2-1) +5(x^2 - 1)=
(x^2- 1)(x+5)=(*)
(x-1)(x+1)(x+5)
(*) A^2 - B^2 =(A-B)(A +B)

Answer:
Step-by-step explanation:
The answer is Choice (A)
to find the exact middle between the two points, we must find the midpoint in the x-direction and the y-direction.
In the x-direction, the middle of A and C is at (a+b)/2
In the y-direction, the middle of A and C is c/2
Hope that helps!

Answer:
<em>B.) ABC is similar to DEF because 6/4 = 12/8 = 9/6!</em>
Step-by-step explanation:
ABC is similar to DEF because the ratio of there sides are the same! If two triangles have three pairs of sides in the same ratio, then the triangles are similar.
The ratio stays 1.5 in all instances! These tringles are similar.
