Answer:
Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4
1) Multiply 12 by 4.1.
2) Divide 49.2 by 2.
3) Multiply 24.6 by 9.

Answer:
Step-by-step explanation:
This is <em>a separable differential equation</em>. Rearranging terms in the equation gives
Integration on both sides gives
where 
is a constant of integration.
The steps for solving the integral on the right hand side are presented below.
Therefore,
Multiply both sides by 
By taking exponents, we obtain
Isolate 
.
Since 
when 
, we obtain an initial condition 
.
We can use it to find the numeric value of the constant .
Substituting 
for and 
in the equation gives
Therefore, the solution of the given differential equation is
Answer:

Step-by-step explanation:
x(2x) - 4(2x) + x(3) - 4(3)
= 2x² - 8x + 3x -12
= 2x²-5x-12
