Answer:
2x^3 + 3x^2 - 11x - 6.
Step-by-step explanation:
(2x+1) (x-2) (x+3)
= (2x + 1)[x(x + 3)-2(x + 3)]
= (2x + 1)(x^2 + x - 6)
= 2x(x^2 + x - 6) + 1(x^2 + x - 6)
= 2x^3 + 2x^2 - 12x + x^2 + x - 6
= 2x^3 + 3x^2 - 11x - 6.
Good morning,
Answer:
<h2>=2x³+3x²-11x-6.</h2>
Step-by-step explanation:
(2x+1) (x-2) (x+3)
= (2x+1) [(x-2) (x+3)]
= (2x+1) [x²+3x-2x-6]
= (2x+1) [x²+x—6]
= 2x³+2x²-12x+x²+x-6
=2x³+3x²-11x-6.

Answer:
Step-by-step explanation:
294% = 2.94 = 2 and .94 = 2 94/100 = 2 47/50
13. y > 2
14. x - 13 < 9;; x < 22
15. x + 86 < 263;; at most 177 pounds
-7x + y = -22
-7*4 + y = -22
y = -22 + 28
y = 6
10/25 and 6/15
10/25=2/5 and 6/15=2/5
