Factor the following expression...
x^2 - 2x - 3

Answers

Answer 1
Answer: Trying to factor by splitting the middle term

 1.1     Factoring  x2-2x-3 

The first term is,  x2  its coefficient is  1 .
The middle term is,  -2x  its coefficient is  -2 .
The last term, "the constant", is  -3 

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3 

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   -2 .

     -3   +   1   =   -2   That's it


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  1 
                     x2 - 3x + 1x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :
                    x • (x-3)
              Add up the last 2 terms, pulling out common factors :
                     1 • (x-3)
Step-5 : Add up the four terms of step 4 :
                    (x+1)  •  (x-3)
             Which is the desired factorization

Final result : (x + 1) • (x - 3) 

hope this helps hope i am brainliest i need it

What adds to -2 and multiplies to 15

Answers

If you meant -15

the -5 and 3

3-5=-2
-3x5=-15
(-5) + 3 = -2(-5) × 3 = -15I can't think of one that multiplies to give positive 15 and also adds to give -2.

Is the histogram uniform, symmetric, or skewed?

Answers

A histogram is a graphical representation of data. A histogram is uniform when it forms almost a straight, horizontal line. It is symmetric when it forms a bell shape, equal parts to both sides. It is skewed when most of the data falls to the left or right.

With reference to the image attached below, a histogram is uniform if it forms a straight line, symmetrical if it forms a bell-shaped curve, and skewed.

What is a Uniform, Symmetric, or Skewed Histogram?

When a histogram is uniform, it appears like a straight line is formed. When the histogram is symmetrical, it forms a normal bell-shaped curve as shown in the image attached below.

Also, the image attached below shows how a skewed histogram will appear like.

In summary, a histogram is uniform if it forms a straight line, symmetrical if it forms a bell-shaped curve, and skewed as shown in the image below.

add 18 each time
first term is -108

an=a1+d(n-1)
d=common difference
a1=startng term

an=-108+18(n-1)

31 term
a31=-108+18(31-1)
a31=-108+18(30)
a31=-108+540

Answer:

V =12.167 cm^3

Step-by-step explanation:

V = s^3 is the volume of a cube where s is the side length

The side length of the cube is 2.3 cm

V = ( 2.3  cm) ^3

V =12.167 cm^3

Hey there!

The FORMULA:

V = s^3

Your EQUATION:

v = 2.3^3

SOLVING for the EQUATION

v = 2.3^3

2.3^3 = v

(2.3 cm)^3

≈ 2.3 cm * 2.3 cm * 2.3 cm

≈ 5.29 cm * 2.3 cm

≈ 12.167 cm^3

v ≈ 12.167 cm^3

Therefore, your answer is: 12.167 cm^3

Good luck on your assignment and enjoy your day!
