Answer:
<em>3</em>
Step-by-step explanation:
GCF means greatest common factor. It is the largest number that 3, 15, and 9 are divisible by.
3 is divisible by only 1 and 3
15 is divisible by 1, 3, 5, and 15
9 is divisible by 1, 3, and 9
The largest number 3, 15, and 9 are divisible by is 3.
The GCF of 3, 15, and 9 is 3.
the 2 equations are vertical angles, which mean they are equal to each other.
Set them to equal and solve for X:
x+40 = 3x
Subtract 1x from each side:
40 = 2X
Divide both sides by 2:
X = 40/2
X = 20
Answer: The required solution is
Step-by-step explanation: We are given to solve the following differential equation :
Let us consider that
be an auxiliary solution of equation (i).
Then, we have
Substituting these values in equation (i), we get
So, the general solution of the given equation is
Differentiating with respect to t, we get
According to the given conditions, we have
and
From equation (ii), we get
Thus, the required solution is
