What is the product of 2x - 5 and 3x2 + 5x - 7? Write your answer in standard form.
andrew11 [14]

Answer:

a) 6x³ − 5x² − 39x + 35

b) no

Step-by-step explanation:

(2x − 5) (3x² + 5x − 7)

Distribute:

3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)

Distribute again:

6x³ − 15x² + 10x² − 25x − 14x + 35

Combine like terms:

6x³ − 5x² − 39x + 35

5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

P is the centroid of triangle ABC. AE=21,CD=14, and BF=11<br><br> What is the length of AP
allsm [11]

The length of AP is 14 units

Step-by-step explanation:

The centroid point of a triangle is:

  • The point of intersection of the three medians of the triangle
  • The centroid point divides each median into two segments at a ratio 2 : 1 from its vertex
  • The length of the segment from the vertex to the centroid is \frac{2}{3} of the length of the median
  • The length of the segment from the centroid to the base is \frac{1}{3} of the length of the median

Look to the attached figure

In Δ ABC

∵ D is the mid-point of AB

∵ E is the mid-point of BC

∵ F is the mid-point of AC

∵ AE , BF and CD are the medians of the triangle

∵ AE , BF and CD are intersected at P

∴ P is the centroid of the triangle

- By using the rule above

∴ AP = \frac{2}{3} AE

∵ AE = 21 units

∴ AP = \frac{2}{3} × 21

∴ AP = 14 units

The length of AP is 14 units
