Answer:

11x+1

Step-by-step explanation:

First, lets ignore all the functions it is giving us. Ignore everything not important at this second; sometimes it can cloud some people's ability to process problems.

We need to look. It asks us for area. Area is length times width. We have the area, we have the width, but we need the length. So we need to divide!

\frac{66x^{2} + 17x + 1}{6x+1} Is going to be our equation! Now, we just need to simplify!

First, lets factor the top function!

66 times 1 is 66, so we need two numbers that add to 17 and multiply to 66.

Off the top of my head, 6 and 11 seem like a perfect match! They add to 17, and multiply to 66!

So now lets sub these in for 17x!

66x^{2} + 11x + 6x + 1

Now lets factor!

(66x^{2}  + 11x) ==> 11x(6x + 1)\\(6x + 1) ==> 1(6x+1)\\(11x + 1)(6x+1)

Now lets get back to the original equation!

\frac{(11x+1)(6x+1)}{6x+1}

We can simply cross out the (6x+1), since there is one on each side, leaving us with 11x+1!

So the length of the top surface, h(x) = 11x+1!

Hope this helps!

Answer:

11x + 1

Step-by-step explanation:

f(x) = 66x² + 17x + 1

Factoring:

f(x) = (6x + 1) (11x + 1)

Area of a rectangle is width times length.  So if g(x) = 6x + 1, then h(x) = 11x + 1.

Which function is linear? y = 1/(x + 2) y = x + 2 y = 1/x + 2 y = (x + 2)/(x - 2)
Nataliya [291]
Linear functions are the ones whose graph is a straight line. So if you graph all the answers into desmos you will see which ones are not linear.

y=x+2 is linear.

y=1/(x+2) is the same as y=1/x+2 and those are rational functions

What is the difference between postitive association and positive correlation
OleMash [197]

Answer: Positive correlation is a relationship between two variables in which both variables move in tandem - that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases; or, one variable increases while the other increases.

What's rise over run
olganol [36]
You use "Rise Over Run" to measure how steep a slope is or to discover whether a slope exists at all.

"Rise Over Run" can also be known as the "gradient", "slope" or "tangent".

Rise / Run = (y₂-y₁)/(x₂-x₁) = Opposite / Adjacent

These values can be positive or negative as positive and negative slopes exist in mathematics.

Jeramy took 6 hours to read 222 pages of his book. What is Jeramy’s reading speed
DedPeter [7]

Answer:

37 pages/hour

Step-by-step explanation:

This is a unit rate problem.

You are trying to find the number of pages per hour.

Divide the number of pages by  the number of hours.

222 pages in 6 hours

(222 pages) / (6 hours) = 37 pages/hour
