Answer:

11v^2 - 8v + 1

Step-by-step explanation:

(4v^2 - 5v - 1) + (7v^2 - 3v + 2)

open brackets

4v^2 - 5v - 1 + 7v^2 - 3v + 2

place like terms together (remember signs remain same )

4v^2 + 7v^2 - 5v - 3v + 2 - 1

add or subtract like terms

11v^2 - 8v + 1

Lines x and y are parallel.
densk [106]

On the bottom line, the 106 and number 1 make a straight line and needs to equal 180 degrees.

This means number 1 = 180-106 = 74 degrees.

Because x and y are parallel, the top outside angle is the same as number 1.

6x +8 = 74

Subtract 8 from both sides:

6x = 66

divide both sides by 6:

x = 66 / 6

x = 11

Now you have x, replace x in the equation for 7x-2 to find that angle:

7(11) -2 = 77-2 = 75 degrees.

The three inside angles need to equal 180 degrees.

Angle 2 = 180 - 74 - 75 = 31 degrees.
