Answer:
(-2)
Step-by-step explanation:
We have to find the determinant of the given matrix,
det A = (a - 1)(a² + a + 1) - (a + 1)(a² - a + 1)
= a(a² + a + 1) - 1(a²+ a + 1) - a(a² - a + 1) - 1(a² - a + 1)
= a³ + a² + a - a² - a - 1 - a³ + a² - a - a² + a - 1
= (a³ - a³) + (-a² + a² - a² - a²) - 1 - 1
= -2
Therefore, determinant of the given matrix is (-2).
You Kinda Have To Treat This Like Area and Width Etc. Multiplication Should be Your Answer, But I don't know About the Table Part.

Answer:
Step-by-step explanation:
Figuring out based on $10.00 per hour rental fee.
you would take the number of full hours and multiply by the fee.
5 hours x $10 = $50
for the leftover .5 hours (which is half an hour) you would take the $10 hourly fee and divide it in half.
$10 ÷ 2 = $5 per half hour
$5 x 1 (half hour) = $5
Now add up the total for the 5 hours and the total for the half hour and that is your total cost.

- 2 
- 
First change the two mixed numbers to improper fractions. Multiply the whole number by the denominator then add the numerator to the answer.
Bring the fractions to the same denominator by finding the lowest common multiple of both denominators
Then the answer becomes .
