Answer:
x=0 x=-5 x=2
Step-by-step explanation:
4x3 + 12x2 = 40x
Subtract 40x from each side
4x3 + 12x2 - 40x=0
Factor out 4x from each term
4x( x^2 +3x-10) =0
Factor the term insdie the parentheses
What 2 numbers multiply to -10 and add to 3
5*-2 =-10
5+-2 =3
We have (x+5) (x-2)
Replace that in the equation
4x ( x+5) (x-2) =0
Using the zero product property
4x= 0 x+5 =0 x-2 =0
x=0 x=-5 x=2
Obtuse because it only takes one obtuse angle to make an obtuse triangle
Answer:
B. Equilateral
It is an equilateral triangle
As we can see all sides are equal.
10x ∠-20
x∠-20/10
x∠-2
this is your answer

36 x 3/9.
3/9 = 0.33
0.33 x 36 = 12
