Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30​
Natasha_Volkova [10]

Answer:

P(2)=0 then x-2 is a factor of P(x)

Step-by-step explanation:

To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.

2(2)^3-3(2)^2-17(2)+30

2(8)-3(4)-34+30

16-12-34+30

4-34+30

-30+30

0

Since P(2)=0 then x-2 is a factor

50 Points: Name the similar triangles & Prove the similarity with details
Leno4ka [110]

<u>Let's consider the facts at hand</u>:

  • By Vertical Angle Theorem ⇒ ∠BCE = ∠DCF
  • ∠BEC = ∠DFC
  • Sides BE = DF

<u>Based on the diagram, triangles BCE and triangles DCF are similar</u>

   ⇒ based on the Angle-Angle theorem

      ⇒ since ∠BCE = ∠DCF and ∠BEC = ∠DFC

         ⇒ the two triangles are similar

Hope that helps!

<em>Definitions of Theorem I used:</em>

  • <u><em>Vertical Angle Theorem: </em></u><em>opposite angles of two intersecting lines must be equal</em>
  • <u><em>Angle-Angle Theorem:</em></u><em> if two angles of both triangles are equal, then the given triangles must be similar</em>

In the 2004 season, Seattle's Lauren Jackson was ranked first in the WNBA for total points and points per game. She scored 634 p
Sonja [21]

Using a system of equations, it is found that she made:

  • 141 free throws.
  • 168 two-point field goals.
  • 53 three-point field goals.

For the system, we have that:

  • x is the number of free throws made.
  • y is the number of two-point field goals made.
  • z is the number of three-point field goals made.

She made 362 shots, hence:

x + y + z = 362

She scored 636 points, hence:

x + 2y + 3z = 636

  • Observation: I used 636 as there would not be a solution(number of field goals cannot be a fraction) if 634 was used.

She made 27 more 2-point field goals than free throws, hence:

y = x + 27

Then:

x + y + z = 362

x + x + 27 + z = 362

2x + z = 335

z = 335 - 2x

x + 2y + 3z = 636

x + 2(x + 27) + 3z = 634

3x + 3z = 582

x + z = 194

z = 194 - x

Equaling both equations for z, finding x:

335 - 2x = 194 - x

x = 141

Then, to find y and z:

y = x + 27 = 141 + 27 = 168

z = 194 - x = 194 - 141 = 53

She made:

  • 141 free throws.
  • 168 two-point field goals.
  • 53 three-point field goals.

Solve by factoring: 2x2 - 5x - 12 = 0
Zepler [3.9K]

Step-by-step explanation:

2 {x}^{2}  - 5x - 12

2 {x}^{2}   - 8x  + 3x - 12

2x(x - 4) + 3(x - 4)

2x  + 3 = 0 \:  \: x - 4 = 0

x =  \frac{ - 3}{2}  \:  \: x =4
