Correct option is

Correct option isC

Correct option isC3(2x+1)

Correct option isC3(2x+1)(fog)(x)=f(g(x))=2(3x+2)−1=6x+4−1=6x+3=3(2x+1)

If the area of a rectangle is 12cm2 what could its length be and its width?
lawyer [7]
Hello, 

We know that th formula for the area of a rectangle is: A=b*h
Now, the problem in this excercise is that there is no restriction on the values that b and h can take, so, they can take any value provided that it meets:  b*h=12 cm^{2}
for example:
lenght=  \frac{12}{3}cm \,\,\,\,\,\,and\,\,\,\,width= 3 cm \\  \\ A=\frac{12}{3}cm*3cm \\ A=12 cm^{2}

But if they can only take intenger values, what we have to do is to descompose 12, and then we can analyze the possible solutions.

12   |  2
  6   |  2
  3   |  3
  1

12= 2 *2*3

first option:
12=4*3

Answer: lenght= 4cm   and   width= 3cm  or vice versa

second option:
12=2*6

Answer: lenght= 6cm   and   width= 2cm  <span>or vice versa</span>

Line segment AB has endpoints A(1, 2) and B(5, 3). Find the coordinates of the point that divides the line segment directed from
ikadub [295]

Now despite what you may think, <u>1:3 is not 1/3 in this situation,</u> but rather it's "1 equal part to 3 equal parts", which is a total of 4 equal parts. <u>In short, they want the point that is at the 1/4 mark from A to B.</u>

Firstly, how many units apart is 1 to 5 (the x-coordinates)? That would be 4 units apart. Multiply 1/4 by 4:

\frac{1}{4}\times \frac{4}{1}=\frac{4}{4}=1

Next, how many units apart is 2 to 3 (the y-coordinates)? That would be 1 unit apart. Multiply 1/4 by 1:

\frac{1}{4}\times \frac{1}{1}=\frac{1}{4}

Next, since from 1 to 5 you are <u>increasing</u>, add 1 to 1.

1+1=2

2 is the x-coordinate of the new point.

Next, since from 2 to 3 you are <u>increasing</u>, add 1/4 to 2.

2+\frac{1}{4}=2\frac{1}{4}=\frac{9}{4}

9/4 is the y-coordinate of the new point.

<u>Putting it together, the point which divides AB into a 1:3 ratio is (2, 9/4), or D.</u>

-8.1

Step-by-step explanation:

\frac{ - 4}{9} x + 2.4 = 6

<em>Times </em><em>all </em><em>by </em><em>9</em><em> </em><em>to </em><em>get </em><em>rid </em><em>of </em><em>fraction</em>

<em>- 4x + 21.6 = 54</em>

<em>Take </em><em>2</em><em>1</em><em>.</em><em>6</em><em> </em><em>away</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

<em>- 4x = 32.4</em>

<em>Divide</em><em> </em><em>by </em><em>-</em><em>4</em>

<em>x =  - 8.1</em>
