Factor completely 2x3 + 8x2 + 3x + 12.
goblinko [34]

Answer:

(2x^2+3)(x+4).

Step-by-step explanation:

2x^3+8x^2+3x+12

We need to find the factors of given equation;

Solution:

On Solving the above equation we get;

Now First we will take common factor from first 2 terms which is 2x^2 we get;

2x^2(x+4) + 3x+12

Now we will take the common factor from the last 2 terms which is 3 we get;

2x^2(x+4) + 3(x+4)

Here we get 2 terms in which (x+4) is common factor.

(x+4)(2x^2+3)

Hence After factorizing the given equation we get (2x^2+3)(x+4).

What is the equation of the line? Graph of a line in the coordinate plane through the origin and the point begin ordered pair 1
Margarita [4]

Here the line passes through (0,0) and (1,3).

First we need to find the slope , and for that we need to use the following formula

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

On substituting the values from the point, we will get

m=\frac{3-0}{1-0}=3

Now we will use slope intercept form, which is

y = mx+ b

Where m is the slope and b is the y intercept

And on substituting the values of x and y from the point (1,3) and slope, m = 3, we will get

3 = 3(1)+b

3=3+b

b =0

Substituting the values of m and b in the slope intercept form, we will get

y= 3x

Can i please get help with this question?
Aleonysh [2.5K]

1,5 . n = 13,65


We know:


1,5=\frac{15}{10}

and

13,65=\frac{1365}{100}


So,


\frac{15}{10}.n=\frac{1365}{100}


Pass \frac{15}{10} as division.


n = \frac{\frac{1365}{100}}{\frac{15}{10}}


Btw, we also know:


\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}


So,


n = \frac{\frac{1365}{100}}{\frac{15}{10}}

n = \frac{1365.10}{100.15}

n = \frac{13650}{1500}

n = \frac{91}{10}

n = 9,1

I'm having a hard time on this problem. Plz help. Will mark brainliest.
Grace [21]

Answer:

<h2>y = 31</h2>

Step-by-step explanation:

We know: opposite angles in a parallelogram have the same measure.

Therefore we have the equation:

x+y=87+y            <em>subtract y from both sides</em>

x=87

We know: the sum of the angle measures in the triangle is 180°.

Therefore we have the equation:

42+(x+y)+20=180          <em>subtitute x = 87</em>

42+87+y+20=180

149+y=180              <em>subtract 149 from both sides</em>

y=31
