Answer:
10v² - 27v - 17vx - 20x²
Step-by-step explanation:
Given
(5v + 4x)(2v - 5x - 3)
Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is
5v(2v - 5x - 3) + 4x(2v - 5x - 3) ← distribute both parenthesis
= 10v² - 25vx - 15v + 8vx - 20x² - 12x ← collect like terms
= 10v² - 15v - 17vx - 12x - 20x²
Counterexample:

4 is not a prime number. So, it's false.
(4x - 2)* 6(2x + 7)
=(4x - 2)(12x + 42)
= 4x(12x + 42) - 2(12x + 42
= 48x^2 + 168x - 24x - 84
= 48x^2 + 144x - 84 Answer
