Answer: k = 12
<u>Step-by-step explanation:</u>
x² + kx + 36 = 0
In order for x to have exactly one solution, it must be a perfect square.
(x + √36)² = 0
(x + 6)² = 0
(x + 6)(x + 6) = 0
x² + 6x + 6x + 36 = 0
x² + 12x + 36 = 0
k = 12
I believe the answer to your question is the distributive property

Answer:
A: 11,13, 290
B: 7,24,25
Step-by-step explanation:
A &B both form a right triangle not C
Answer:
Yes
Step-by-step explanation:
We are given that a function 
We have to find that given function is an explicit solution to the linear equation

If given function is an explicit solution of given linear equation then it satisfied the given differential equation
Differentiate w.r.t x
Then we get 
Again differentiate w.r.t x
Then we get

Substitute all values in the given differential equation

=
Hence, given function is an explicit solution of given differential equation.
Therefore, answer is yes.
