The length of a rectangular backyard is represented by 4x + 10, and the width is represented by 2x + 5. An inground swimming pool with an area of 2x² will be installed tomorrow. Write an expression to
represent the remaining area of the backyard.
(1) 8x² + 40x + 50
(3) 2x² + 6x + 15
(2) 6x² + 40x + 50
(4) 6x² + 50

(2) 6x^2+40x +50

Step-by-step explanation:

(4x+10)*(2x+5) = 8x^2 +40+50

minus 2x^2

=6x^2 +40 +50

50=33x+22

step-by-step explanation:

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
