Answer:

a. 16x + 9x + 8x + 11

b. 33x + 11 (or 11(3x + 1) if this is asking for a factored expression)

Step-by-step explanation:

Looking at the directions, part a tells us to use all 4 side lengths, so the equation for part a is 16x + 9x + 8x + 11.

Now to simplify that expression.

16x + 9x + 8x + 11

<em>Step: Combine 16x, 9x, and 8x. I'll go from left to right.</em>

25x + 8x + 11

33x + 11

(What you see above this statement is my answer, but work is below if this is asking for a factored expression.)

11: 1, 11

33: 1, 3, 11, 33

<em>Now divide both 33x and 11 by 11 and put the 11 outside the parentheses.</em>

33x/11 = 3x

11/11 = 1

11(3x + 1)

Answer:

C = n + 2

Step-by-step explanation:

Well looking at the line on the graph we can see that the y intercept is 2 because the y intercept is the point in the line that touches the y axis.

And the slope is how fat away each points are from each other on a line so we can find the slope by using two points on the line, we can use (1,3) and (2,4).

So we set up the formula like this $\frac{y^2-y^1}{x^2-x^1}$ .

And now we gotta plug in the numbers and solve so the answer is 4-3 = 1 and 2-1 = 1 so the slope is 1.

And we can’t write that as just n.

So the answer is C = n + 2.

For proof look at the image below.

(x-9)(x+2) <br> see if u can find it

ycow [4]

Answer:

x^2 -7x-18

Step-by-step explanation:

(x-9)(x+2)

FOIL

first x*x = x^2

outer 2x

inner -9x

last -9*2 =-18

Add together

x^2 +2x-9x-18

Combine like terms

x^2 -7x-18

Pumping stations deliver oil at the rate modeled by the function D, given by d of t equals the quotient of 5 times t and the qua

goblinko [34]

<h2>Hello!</h2>

The answer is: There is a total of 5.797 gallons pumped during the given period.

To solve this equation, we need to integrate the function at the given period (from t=0 to t=4)

The given function is:

$D(t)=\frac{5t}{1+3t}$

So, the integral will be:

$\int\limits^4_0 {\frac{5t}{1+3t}} \ dx$

So, integrating we have:

$\int\limits^4_0 {\frac{5t}{1+3t}} \ dt=5\int\limits^4_0 {\frac{t}{1+3t}} \ dx$

Performing a change of variable, we have:

$1+t=u\\du=1+3t=3dt\\x=\frac{u-1}{3}$

Then, substituting, we have:

$\frac{5}{3}*\frac{1}{3}\int\limits^4_0 {\frac{u-1}{u}} \ du=\frac{5}{9} \int\limits^4_0 {\frac{u-1}{u}} \ du\\\\\frac{5}{9} \int\limits^4_0 {\frac{u-1}{u}} \ du=\frac{5}{9} \int\limits^4_0 {\frac{u}{u} -\frac{1}{u } \ du$

$\frac{5}{9} \int\limits^4_0 {(\frac{u}{u} -\frac{1}{u } )\ du=\frac{5}{9} \int\limits^4_0 {(1 -\frac{1}{u } )$

$\frac{5}{9} \int\limits^4_0 {(1 -\frac{1}{u })\ du=\frac{5}{9} \int\limits^4_0 {(1 )\ du- \frac{5}{9} \int\limits^4_0 {(\frac{1}{u })\ du$

$\frac{5}{9} \int\limits^4_0 {(1 )\ du- \frac{5}{9} \int\limits^4_0 {(\frac{1}{u })\ du=\frac{5}{9} (u-lnu)/[0,4]$

Reverting the change of variable, we have:

$\frac{5}{9} (u-lnu)/[0,4]=\frac{5}{9}((1+3t)-ln(1+3t))/[0,4]$

Then, evaluating we have:

$\frac{5}{9}((1+3t)-ln(1+3t))[0,4]=(\frac{5}{9}((1+3(4)-ln(1+3(4)))-(\frac{5}{9}((1+3(0)-ln(1+3(0)))=\frac{5}{9}(10.435)-\frac{5}{9}(1)=5.797$

So, there is a total of 5.797 gallons pumped during the given period.

Have a nice day!

Solve 20p−60 using GCF

ExtremeBDS [4]

Greatest common factor between each term is 20, so you'd divide both by 20 to reduce this to 20(p - 3).
