t=D/r
Divide r by both sides to get t by itself.
X = 6 after distributing then adding 39 to both sides and then divide by 13
option a as 3 is outside of bracket it will be multiplied by what is in bracket sot the answer will equivalent to question
Answer:
The constant of variation for the given quadratic equation is, 30
Step-by-step explanation:
One of the form of a quadratic equation is written as:
....[1]
where k is the coefficient and for this case the constant of variation.
In order to obtain the answer for the given equation, we write the given equation to the form above.
or
or

Comparing this equation with equation [1], to get the value of k;
k=30.
therefore, the constant of variation is, 30.
