Find the product of (2x − 3)(2x2 + 7x − 1).
A:4x3 − 6x2 − 9x + 3
B:4x3 + 8x2 − 23x + 3
C:4x3 + 20x2 − 9x + 3
D:4x3 − 6x2 − 23x + 3

B. 4 x^3 + 8 x^2 - 23 x + 3

Step-by-step explanation:

Expand the following:

(2 x - 3) (2 x^2 + 7 x - 1)

| | | | 2 x | - | 3

| | 2 x^2 | + | 7 x | - | 1

| | | | -2 x | + | 3

| | 14 x^2 | - | 21 x | + | 0

4 x^3 | - | 6 x^2 | + | 0 | + | 0

4 x^3 | + | 8 x^2 | - | 23 x | + | 3:

4 x^3 + 8 x^2 - 23 x + 3

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
