Answer:

No, I will not simplify 3² first.

Rather I would simplify (12-3) first, i.e., 9.

Then simplify 9² which gives the answer 81.

Step-by-step explanation:

(12-3)²
= 9²
= 81

Answer:

x=-26

Step-by-step explanation:

Subtract 45 from both sides.

-85-45=5x

Simplify -85-45 to -130

-130=5x

Divide both sides by 5.

-130/5=x

Simplify 130/5 to 26

-26=x
