Answer:
1.23 meters
Step-by-step explanation:
7 & 8/10 or 78/10 ( which is the same thing)
Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
Solve for x by simplifying both sides of the equation then isolating teh varible.
your answer = - 1/7
