Answer:

A. 4x² - 2x + 11

Step-by-step explanation:

(4x² + 6) - (2x - 5) =

Drop the first set of parentheses since it is unnecessary.

= 4x² + 6 - (2x - 5)

To drop the second set of parentheses, you must change every sign inside the parentheses.

= 4x² + 6 - 2x + 5

Now combine like terms.

= 4x² - 2x + 11

Solve for x. Show each step of the solution. 5.5(8-x)+44=104-3.5(3x+24)
earnstyle [38]
5.5 ( 8 - x ) + 44 = 104 - 3.5 ( 3x + 24 )

Distribute 5.5 through the parenthesis.

44 - 5.5x + 44 = 104 - 10.5x - 84

Add the numbers.

88 - 5.5x = 20 - 10.5x

Move variable to the left side and change its sign.

88 - 5.5x + 10.5x = 20
-5.5x + 10.5x = 20 -88

Collect like terms.

5x = 20 - 88

Calculate the sum or difference. 

5x = - 68

Divide both sides by 5.

x = - 68 / 5
