Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:

$x^2 + 18x + 81$

$x^2 +3x + 27x + 81$

Group:

$(x^2 +3x) (27x + 81)$

Take out GCF (Greates Common Factor):

x(x + 3) 27(x + 3)

(x + 27) (x + 3)

What is the oblique asymptote of the function f(x) x^2+x-2/x+1

Mamont248 [21]

$f(x)=\displaystyle\frac{x^2+x-2}{x+1}=\frac{x(x+1)-2}{x+1}=x-\frac{2}{x+1}
$

$\displaystyle\lim_{x\to\infty}\left\{f(x)-x \right\}=\lim_{x\to\infty}\frac{2}{x+1}=\lim_{x\to\infty}\frac{\displaystyle\frac{2}{x}}{1+\displaystyle\frac{1}{x}}
=0$

Consequently, the limit of $f(x)$ as x approaches infinity is $x$ .

In other words, $f(x)$ approaches the line y=x,

so oblique asymptote is y=x.

HELP PLS WITH PYTHAGOREAN THEOREM

Darina [25.2K]

Answer:

100 ft

Step-by-step explanation:

We need to find the diagonal ( or hypotenuse)

We can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

80^2 + 60^2 = c^2

6400+3600 = c^2

10000 = c^2

Taking the square root of each side

sqrt(10000) = sqrt(c^2)

100 = c
