He made $357 I believe. You would do 8.50x36=306 then 3x17=51. Then you add 306+51=357

=. What does the expression (x+3)(9) represent? Why?
tresset_1 [31]
Because when you multiply the 9 by x you get 9x and when you multiply the 9 by 3 you get 27. So then your final answer would be 9x + 27.
I hope this helps!! :)

I am completely lost.
Lesechka [4]
The surface area of a solid is just the total area of all its faces. We know a cube has 6 identical faces with area s^2 where s is the side length.

So 6s^2 is the surface area. We can use this to find s.

6s^2 = 600

s^2 = 100

s = 10 cm

Assuming part a is correct, how do you do b and c?
zubka84 [21]

Step-by-step explanation:

B. Yes, we are 99% confident that the population mean is within the interval.

C. Yes, 225 is below the interval minimum, so it is reasonable to conclude the average cholesterol level is greater than 225 mg/dl.

D. No.  Increasing the sample size would decrease the margin of error, so the ends of the interval would move closer to the sample mean of 251.9.  So the interval minimum would still be higher than 225.

F(x) = -x - 3 Find f(-4) f(-4) = -(-4) -3
skelet666 [1.2K]

Answer:

\boxed{ \bold{ \boxed{ \sf{f( - 4) = 1}}}}

Step-by-step explanation:

Given, f ( x ) = - x - 3

Let's find the value of f ( - 4 )

\sf{f( - 4) =  - ( - 4) - 3}

We know that , ( - ) \times ( - ) = ( + )

⇒\sf{ 4 - 3}

Subtract 3 from 4

⇒\sf{1}

Hope I helped!

Best regards!!
