Answer:
second option
Step-by-step explanation:
Given
+ 6x² + 5 = 0
let u = x², then
u² + 6u + 5 = 0 ← in standard form
(u + 1)(u + 5) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 1 = 0 ⇒ u = - 1
u + 5 = 0 ⇒ u = - 5
Change u back into terms of x, that is
x² = - 1 ( take the square root of both sides )
x = ± 
= ± i ( noting that = i ), and
x² = - 5 ( take the square root of both sides )
x = ± 
= ± 
= ± 
× = ± i
Solutions are x = ± i and x = ± i
ANSWER
The particular solution is:
EXPLANATION
The given Ordinary Differential Equation is
The general solution to this Differential equation is:
To find the particular solution, we need to apply the initial conditions (ICs)
This implies that;
Hence the particular solution is
I think that the answer would be two triangles.
Answer:
76cm^2
Step-by-step explanation:
Separate the shape into two different rectangles. Then add the area of the rectangles together.
4 x 4 = 16
6 x 10 = 60
16 + 60 = 76
Answer:
40.5
Step-by-step explanation:
a cube has 6 faces so 6.75 x 6 = 40.5
