Step-by-step explanation:

Given point (-2 , 4) and slope (m) = 2

The equation of line is given

y - y1 = m ( x - x1)

y - 4 = 2 ( x +2)

y - 4 = 2x + 4

2x + 4 + 4-y = 0

2x - y + 8 = 0

Which is the required equation

8x - 2x(x+1) = 2(3x-1)

First, expand to remove parenthesis. / Your problem should look like:

8x - 2x - 2 = 6x - 2

Second, subtract 8x - 2x -2 to get 6x - 2. / Your problem should look like:

6x - 2 = 6x - 2

Third, both sides are equal, so there are infinite solutions. The equation is always true, meaning identity

Answer: Infinite solutions

Hey can you please help me posted picture of question

Ira Lisetskai [31]

Answer:
40x² + 65x + 25

Explanation:
We will just multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.

This would be done as follows:
(5x + 5)(8x + 5)
5x(8x) + 5x(5) + 5(8x) + 5(5)
40x² + 25x + 40x + 25
40x² + 65x + 25

Hope this helps :)
