Answer:
B
Step-by-step explanation:
Matches all specified equations.
Answer: I think it is 364.80
Factorise to get (x - 0.5)^3 = 0
The equation has root 1/2 with multiplicity 3.
Step-by-step explanation:
First, let us find the magic sum in each row/column/diagonal.
Sum of numbers from 1 to 9 = 45.
45 divide by 3 rows = 15 each row.
The magic sum is 15.
For the diagonals, we have:
8 + 5 + x = Magic sum = 15,
6 + 5 + y = Magic sum = 15.
Therefore x = 2 and y = 4.
Answer: X-Intercepts: x= <u>-5</u> x= <u>5</u>
