Hello :
<span> x4 − 9x2 − 4x + 12 = x²(x²-9)-4(x-3)
=x²(x-3)(x+3)-4(x-3)
= (x-3)(x²(x+3)-4)
= (x-3)(x3+3x²-4)
= (x-3)(x-1)(x²+4x+4)
</span>x4 − 9x2 − 4x + 12 = (x-3)(x-1) (x+2)²
<span> potential roots is : 3 ; 1 :-2</span>
Answer:
The length of Mai's bike ride was 2.1 times the length of Noah's ride.
Step-by-step explanation:
Mai biked 5 1/4 miles today
So he biked, in miles:

Noah biked 2 1/2 miles.
So, in miles, he biked:

How many times the length of Noah’s bike ride was Mai’s bike ride?
We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So

The length of Mai's bike ride was 2.1 times the length of Noah's ride.
Answer:
Quadrilaterally-faced hexahedron
12 edges and 8 vertices
Step-by-step explanation:
This would be a regular dice which is used in the vast majority of board games that exist. The shape of this is formally known as a Quadrilaterally-faced hexahedron, also known as a cuboid. There are various versions of a hexahedron such as a Rectangular cuboid or a Rhombohedron, one of which has rectangular faces and the other has rhomboid faces. The hexahedron has 12 edges and 8 vertices in total
Answer:
C
Step-by-step explanation:
Put it into slope form
y=mx+b
distribute the -3 from (y+1) = -3 (x-1)
y+1 = -3x +3
subtract the 1
y=-3x +2
Answer:
x = - 22, x = 4
Step-by-step explanation:
Given
(x + 9)² = 169 ( take the square root of both sides )
x + 9 = ±
= ± 13 ( subtract 9 from both sides )
x = - 9 ± 13
Thus
x = - 9 - 13 = - 22
x = - 9 + 13 = 4
