Answer:
A
Step-by-step explanation:
a^2 + 144^2 = 145^2
a^2 + 20736 = 21025
a^2 = 289
a = sqrt(289)

Answer:
Kind Note:
This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.
Step-by-step explanation:
This question involves the use of 'system of equations'.
3x - 2y = 44
- => (-3x + 3x) + (-7y - 2y) = (8 + 44)
- => -9y = 52
- => y = -52/9 (No further check required)
Since the y-intercept is valid, the system of equations has one solution.
Hence, this system of equations has one solution.
Hoped this helped!
