Find all factors of 2x^3-3x^2-2x
Nesterboy [21]

ANSWER:

x, 2x + 1, x -2

STEP-BY-STEP EXPLANATION:

We have the following expression:

2x^3-3x^2-2x

We simplify as follows to determine the factors:

\begin{gathered} \text{ We factor the common term:} \\  \\ x\left(2x^2-3x-2\right) \\  \\ \text{ Now we factor the following term} \\  \\ 2x^2-3x-2 \\  \\ -3x=x-4x \\  \\ 2x^2+x-4x-2 \\  \\ \left(2x^2+x\right)+\left(-4x-2\right) \\  \\ x\left(2x+1\right)-2\left(2x+1\right) \\  \\ \left(2x+1\right)\left(x-2\right) \\  \\ \text{ Therefore:} \\  \\ 2x^3-3x^2-2x=x\left(2x+1\right)\left(x-2\right) \end{gathered}

The factors would be x, 2x + 1, x -2

Convert from DMS (degrees, minutes, seconds) to decimal form (degrees)
tino4ka555 [31]
All I remember is:  1° (degree) = 60' (minute) = 3600" (second) and use the given numbers to put on the..... d° m' s"........dd = d + m/60 + s/3600

1) 118°44'15" => 118/1 + 44/60 + 15/3600 = 118.7375 

same thing with 
2) <span>48°30'36" => 48 + 30/60 + 36/3600 = 48.51</span>

Jose receives $1270 per year from three
salantis [7]

The answer is. $1500.

Let x represent the amount invested at 5%, then  is the amount invested at 8%, and  is the amount invested at 6%. Since the total return is $1270:

let money invested at 5%= x

money invested at 6%

= 20000- (X+X-1500)

21500-2x

Total interest for 1 year.

x×5/100+ (x-1500)×8/100+(21500-2x)×6/100 = 1270

5x/100+8(x-1500)/100+(21500-2x)6/100=1270

5x+8x-12000+129000-12x = 127000

x+117000 = 127000

x = 10000

money invested at 8%

=21500-2×10000

= 1500.

I need help<br> (Find the slope of the line through the given pair of points)<br> (-7,-18),(4,4)
larisa [96]

Answer:

2

Step-by-step explanation:

You can find slope using the slope equation :\frac{y2-y1}{x2-x1}

  • Plug in the two points : \frac{4-(-18)}{4-(-7)}
  • Calculate by adding the numbers: \frac{22}{11}
  • Reduce the fraction : 2

The slope is 2
