Answer:
what is the question? Please ask a question.
12 square + 16 squared = c squared
144 + 256= c squared
400= c squared
C = 20
Answer:
a) x = 10
b) x = -40
c) x = 10, -40
Step-by-step explanation:
a)
Taking 10 to the right hand side 10 becomes positive
So x = 10
b)
Taking 20 to the right hand side 20 becomes negative
Multiplying both sides by 2
So, x = -40
c)
Hence, x = 10, -40
So, two solutions can be provided
That's a 3x3 linear system. Let's do Gaussian elimination
