Answer
because yes
Step-by-step explanation:
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
Answer:
The expression is not correctly given. However If you want the quotient of 0.2 divided by 0.382. This would be the correct answer

Hope thai helps!
please like if I'd does help! (:
The formule is about area of a circle.

We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get


Taking square root on both sides, we get


(1) will write us of the following form

(2) [do not it need explanation]

(3) Left place variable "y" and right place, variable "x" like this

(4) Integrate both members

(5) Solve us the integrals

(6) Isolate variable "y"

C: any cosntant
