Use Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
b^2 + 2b * 12 + 12^2
Simplify 12^2 to 144
b^2 + 2b * 12 + 144
Simplify 2b * 12 to 24b
b^2 + 24b + 144
Answer:
Step-by-step explanation:
You can start this in may ways but let's start by isolating one of the parenthesis:
x (x² - 5) = - (x - 3)
x³ - 5x = -x + 3 (here I multiplied x for what's inside the parenthesis and the "minus" signal by the other parenthesis which was (x - 3))
x³ - 5x + x = 3
x³ -4x = 3
x³ -4x -3 = 0 (now this right here is a "depressed cubic equation" and it's one of the toughest sit of all time, so good luck with that, you might wanna take a look at this:
ytb/watch?v=rNDy2ZFvG1E
or maybe I'm doing something wrong and it's simpler than that, but whaterver...)

Answer:
$25830
Step-by-step explanation:
If 100% of the car price is 24,600 , then you can imagine that extra 5% being added to this
100 + 5 = 105
So you need to find what 105% of the cost was.
To do this you can use the percentage formula:
Amount x 
Now, you can simply plug the values into this
24,600 x 
24600 x 1.05 = 25830
<h3>So the total cost including tax would be $25830!</h3><h3 /><h2>Hope this helps!</h2>
So first,
$22.50 * .20= 4.5
Then, since is 20% off you subtract the percentage you get in which this case, it's 4.5.
$22.50 - 4.5 = $18
So the Jacket is $18.00!
Hope this helps, have a good day. c;
