Subtract 7x + 2 from –5x2 – 2x.

When 7x + 2 is subtracted from –5x² – 2x, the result is –5x² – 9x – 2

To carry out operations in algebra, we must understand that only like terms can either be summed up or subtracted.

(–5x² – 2x) – (7x + 2)

Clear the bracket

–5x² – 2x – 7x – 2

–5x² – 9x – 2

Thus, when 7x + 2 is subtracted from –5x² – 2x, the result obtained is –5x² – 9x – 2.

Step-by-step explanation:

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

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.
