Answer:

$x^3+8x^2+2x+1$

Step-by-step explanation:

Combine like terms (terms with the same exponent).

$x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1$

"Standard form" means to list terms so the exponents go from high to low (descending order).

The intersection of roads s and t creates a 44.4 angle what are the complementary

Lady_Fox [76]

Two angles are complementary when their sum is 90 degrees and supplementary when their sum is 180 degrees

Thus for angle 44.4 degrees, the complementary is 90 - 44.4 = 45.6 and the supplementary is 180 - 44.4 = 135.6

Therefore, t<span>he complementary angle is 45.6 and the supplementary angle is 135.6</span>

- What is the complete factorization of 4x2 – 24xy + 36y2 ?

Rzqust [24]

<u>Answer: </u>

The complete factorization of $4 x^{2}-24 x y+36 y^{2}$ are 4(x-3y)(x+3y)

<u>Solution:</u>

Given Data:

$4 x^{2}-24 x y+36 y^{2}$

Take common value in all the three term.so we take 4 as common term in the above expression

$4 x^{2}-24 x y+36 y^{2}=4\left(x^{2}-6 x y+9 y^{2}\right)$

Now factorize the expression $\left(x^{2}-6 x y+9 y^{2}\right)$

Find the two numbers, whose product should be 9 and sum should be -6.

-3,-3 are the numbers which satisfy the above condition.

When we add -3-3=Sum is 6

Product of -3 $\times$ -3= 9

-3 , -3 satisfies the condition.

So the expression will become as $x^{2}-6 x y+9 y^{2}$ = $x^{2}-3 x y-3 x y+9 y^{2}$

Take the common term

x(x-3y)+3y(x-3y)

(x-3y)(x+3y)

hence the complete factorization of $4 x^{2}-24 x y+36 y^{2}$ are 4(x-3y)(x+3y)

It takes 25 minutes to fry a burger at Jill street, how long will it take to fry 13 burgers

Misha Larkins [42]

Answer:

325 minutes

Step-by-step explanation:

We can use a ratio to solve

25 minutes x minutes

------------------ = ---------------

1 burger 13 burgers

Using cross products

25*13 = 1x

325 = x

325 minutes
