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
Answer:
144
Step-by-step explanation:
12x12=144-1=143+1=144
Hope this helps!
The area of a triangle can be shown in the equation Area=1/2(base)(height). Since you are given area and height, you can just solve for the base.
6=1/2(base)(4) ---> 6=2(base) ---> base=3
