- $b^{4}$ + 6 $b^{3}$

divide each term on the numerator by 7b

= - 7 $b^{5}$ / 7b + 42 $b^{4}$ / 7b

= - $b^{4}$ + 6 $b^{3}$

A polynomial has been factored, as shown below: f(x) = (x − 6)(x + 5)(x − 9) What are the zeros of the polynomial? (5 points)

x=6, x=−5 or x=9

Explanation:

f(x)=(x−6)(x+5)(x−9)

If all of the linear factors are non-zero, then so is their product f(x).

If any of the linear factors is zero, then so is their product f(x).

Answer:

At first, we have 3 expressions that are equal.

$3(2+7) - 9 \cdot 7= 3+8 \cdot 2 \cdot 2 - 4$

$6+21 - 63= 3+32 - 4$

$-36=31$

$-36\neq 31$

This is not true.

Sarah needs to have a plumber come to her house and fix a leaky faucet in her bathroom. The plumber charges $50 to come to her h

klio [65]

Answer:

Sarah can have the plumber work on her faucet for six (6) hours maximum

Step-by-step explanation:

As Sarah has only $234.50 in her savings and the plumber charges $50 just to come to her home, so left-over $184.50 of her saving for pay work hours.

Then as the plumber charges $30.75 per hour we have that $\frac{\$ 184.50}{\$ 30.75/h}=6h$ is the maximum amount of hours that Sarah can have the plumber work on her faucet.
