Answer:
x = 1 + sqrt(89) or x = 1 - sqrt(89)
Step-by-step explanation:
Solve for x:
(x - 9) (x + 7) = 25
Expand out terms of the left hand side:
x^2 - 2 x - 63 = 25
Add 63 to both sides:
x^2 - 2 x = 88
Add 1 to both sides:
x^2 - 2 x + 1 = 89
Write the left hand side as a square:
(x - 1)^2 = 89
Take the square root of both sides:
x - 1 = sqrt(89) or x - 1 = -sqrt(89)
Add 1 to both sides:
x = 1 + sqrt(89) or x - 1 = -sqrt(89)
Add 1 to both sides:
Answer: x = 1 + sqrt(89) or x = 1 - sqrt(89)
The sum total of the angles in a triangle is equal to 180° degrees.
I'm pretty sure the coordinates are (-93,-75), (-37,93), (131,37)
Answer:
x > -5
Step-by-step explanation:
Answer:
Hence, the particular solution of the differential equation is 
.
Step-by-step explanation:
This differential equation has separable variable and can be solved by integration. First derivative is now obtained:
, where C is the integration constant.
The integration constant can be found by using the initial condition for the first derivative (
):
The first derivative is 
, and the particular solution is found by integrating one more time and using the initial condition (
):
Hence, the particular solution of the differential equation is .
