(2a - 1) (8a - 5)

= {2a(8a - 5)} - {1(8a - 5)}

= 16a² - 10a - 8a + 5

= 16a² - 18a + 5

$(2a-1)(8a-5)=2a\cdot 8a-2a\cdot 5-8a\cdot 1-5\cdot (-1)=\\ \\=16a^2-10a-8a+5=16a^2-18a +5$

Answer:

$x = 18$

Step-by-step explanation:

Given

$DC=14$

$CE=x$

$DE=32$

Required

Find x

Because C is between D and E;

$DE = DC + CE$

Substitute values for each;

$32 = 14 + x$

Collect Like Terms

$x = 32 - 14$

$x = 18$

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).
