The answer is 7.5 I’m pretty sure
Focus on 12x. Divide the 12 by 2. = 6.
The answer is (x+6)^2. On the right side
On the left side. Use the 6 and square it. 6^2 =36
Answer::: x^2 + 12x + 36 = (x+6)^2
Answer:
120.00
Step-by-step explanation:
Let x be the original price
The price is 10% off, or we pay 90% of the original price
.9 x
Then we have to pay 7% sales tax
.9x * 7%
.9x * .07
.063x is the tax
Add this to the .9x we have to pay for the jacket
.9x + .063x = .963x
This is the cost of the jacket
.963x = 115.56
Divide each side by.963
.963x/.963 = 115.56/.963
x =120.00
The cost of the jacket before discount and tax is 120.00
It decreases hope this helps!

Step-by-step explanation:</h2>
<h2><u>
Exercise 34.</u></h2>
1. Forming the inequality.
Let's make the left side be a calculation of the total earning based on the number of tickets sols. Also, let's make the right side the cost of the dance to compare and find an adecuate minimum value of x.
.
<em>We use the </em><em>"greater or equal to"</em><em> symbol because the side of x expresses the earning of the committee, and these earnings will have to be equal or greater than the cost of the dance to be able to organize the dance.</em>
2. Solving the inequality.

3. Express your results.
, therefore, the dance committee will have to sell at least 82 tickets to be able to cover the cost of the dance.
