Answer:

12 3/8

Step-by-step explanation:

8-1/2+5-1/8

8+5  -1/2 - 1/8

Lets get a common denominator of 8

8+5 - 1/2 *4/4 - 1/8

8+5 - 4/8 - 1/8

Combine the whole numbers and the fractions

13 -5/8

Now we need to borrow from the whole number

12 + 1 - 5/8

12 + 8/8 -5/8

12 +3/8

12 3/8

Given the functions, fx) = x - 8 and g(x) = x2 + x - 1, perform the indicated operation. When applicable, state the domain
adell [148]

Answer:

A

Step-by-step explanation:

(fg)(x) = f(x) × g(x)

= (x - 8)(x² + x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x - 1) - 8(x² + x - 1) ← distribute both parenthesis

= x³ + x² - x - 8x² - 8x + 8 ← collect like terms

= x³ - 7x² - 9x + 8 → A

There are no restrictions on the domain.
