Question

Multiply. (3x - 2)(x + 5) A: 3x² + 17x - 7 B: 3x² + 17x - 10 C: 3x² + 13x - 10 D: 3x² + 6x - 7

Answer 1

Answer:

The answer is C.

Step-by-step explanation:

You have to use Ditributive Law,

$a(m + n) = am + an$

So for this question :

$(3x - 2)(x + 5)$

$= 3x(x) + 3x(5) - 2(x) - 2(5)$

$= 3 {x}^{2} + 15x - 2x - 10$

$= 3 {x}^{2} + 13x - 10$

Answer 2

it is  (3x - 2)*(x + 5) A: 3x² + 17x - 7 B: 3x² + 17x - 10 C: 3x² + 13x - 10 D: 3x² + 6x - 7
