The given equation is 4x^2=x^3+2x.
On the left side it has 4x² and on the right side the expression is x³+2x.
So, if we have any system of equations in which we have these two expression which will be equal to any other variable then we can use that system of equations to find the roots.
Now notice that in option D it's given,
y=4x² and y=x³+2x.
So, if we will equate this equations then we will get the same above equation which will be use to find the roots.
So, D is the correct choice.

Answer:
where n>1
Step-by-step explanation:
Given
![19,22,25, ..](https://tex.z-dn.net/?f=19%2C22%2C25%2C%20..)
Required
Determine the recursive formula
The given sequence shows arithmetic progression (AP).
First, we calculate the common difference (d):
![d = 22 - 19 = 25 - 22](https://tex.z-dn.net/?f=d%20%3D%2022%20-%2019%20%3D%2025%20-%2022)
![d = 3](https://tex.z-dn.net/?f=d%20%3D%203)
The recursive formula of an AP is determined using:
where ![n>1](https://tex.z-dn.net/?f=n%3E1)
Substitute 3 for d
where ![n>1](https://tex.z-dn.net/?f=n%3E1)
Answer:
X=-5
Step-by-step explanation:
Start by isolating the variable to one side. So from here we would add 68 to both sides. we will be left with -8 1/4x = -6.25x+10. Then add 6,25 to both sides to cancel on and get -2x=10. Divide both sides by -2 to get x=-5
