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).

Answer:
15 cubes
Step-by-step explanation:
If volume of the prism = 15
then volume of one cube = 1 × 1 × 1
Volume(1 cube) = 1
Then divide the volume of one cube into the volume of the prism,
15 ÷ 1 = 15 cubes
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
of the length of the median - The length of the segment from the centroid to the base is
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 =
AE
∵ AE = 21 units
∴ AP =
× 21
∴ AP = 14 units
The length of AP is 14 units
