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
3y -1 =13 - 4y
7y = 14
y= 2
The equation has one solution

Answer: last option
Step-by-step explanation:
You know that the weight of his pumpkin 4.9 pounds and that, if he guesses its weight within 0.3 pounds, he will get the pumpkin for free.
Then, to find the minimum weight he can guess in order to get his pumpkin for free, it's necessary to write the expression:
![x-0.3=4.9](https://tex.z-dn.net/?f=x-0.3%3D4.9)
Rewriting it:
![x-4.9=0.3](https://tex.z-dn.net/?f=x-4.9%3D0.3)
To find the maximum weight he can guess in order to get his pumpkin for free, it's necessary to write the expression:
![x+0.3=4.9](https://tex.z-dn.net/?f=x%2B0.3%3D4.9)
Rewriting it:
![x-4.9=-0.3](https://tex.z-dn.net/?f=x-4.9%3D-0.3)
