find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x

16x + 8
10x + 4
12x + 4
8x + 2

Answers

Answer:

12x+4

Step-by-step explanation:

To find the perimeter of any shape you just have to take the sum of all the sides.

In this case you would write:

 4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)

Now you just have to simplify the expression which would give you:

12x+4 (after collecting like terms)

So the final answer will be 12x+4

4x+2+2x=6x+2 which is the same as 12x+4

What is (f+g)(x)?
f(x)=
- 2x2–9x
g(x)=5x
Write your answer as a polynomial or a rational function in simplest form.

Answers

Answer:

-2x²-4x or -2x(x+2)

Step-by-step explanation:

(f+g)(x) means we are adding the values of f(x) and g(x):

f(x) = -2x²-9x

g(x) = 5x

(f+g)(x) = -2x²-9x+5x = -2x²-4x = -2x(x+2)

Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?

B. after how many times will rachel be able to make her desert in 63 minutes?

C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?

Answers

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

600, 1400, 3000, and 5000

Step-by-step explanation:

The profit equation can be simplified.

 P = 350n -(150n +1000)

 P = 200n -1000 . . . . . . . . . collect terms

 P = 200(n -5) . . . . . . . . . . . factor out 200

For the given numbers n, we have ...

 P = 200({8, 12, 20, 30} -5) = 200{3, 7, 15, 25} = {600, 1400, 3000, 5000}

Profits for 8, 12, 20, and 30 customers are 600, 1400, 3000, and 5000, respectively.
