First, use distributive property on the right half.
2 * 5 = 10
2 * 2n = 4n
4n - 9 = 10 + 4n
Add 9 to both sides
4n = 19 + 4n
Subtract 4n from both sides
0 = 19
But thats not true. Therefore, there is no solution.
Answer:
add multiply divide or subtract make sure to use Pemdas then and you should have your answer
Step-by-step explanation:
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
(64)^3/2 = (sqrt(64))^3 = 8^3 = 512.
