Answer: 60,62,64

Step-by-step explanation:

69+62+64=186

I divided 186 by 3 (since triangles have 3 sides) and played with the numbers from there.

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).
