The correct simplification of 8x2(5x 2x2 − 3) is ![16x^{4} +40x^{3} -24x^{2}](https://tex.z-dn.net/?f=16x%5E%7B4%7D%20%2B40x%5E%7B3%7D%20-24x%5E%7B2%7D)
<h3>What do you mean by simplification?</h3>
- Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
- Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
- Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.
The correct simplification of 8x2(5x 2x2 − 3).

Answer:
Yes, it costs $18.99.
Step-by-step explanation:
The game is originally $36 and a game 50% off is 36/2 = $18.
The sale price is $18.
The state charges 5.5% tax which means you pay 105.5% of the sale price.
1.055(18) = 18.99
The final total is 18.99 which means Ron's $19 is enough.

Answer:
x = 11
Step-by-step explanation:
![12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50 \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11](https://tex.z-dn.net/?f=12x%20-%205%20%3D%208x%20-%20x%20%2B%2050%20%5C%5C%2012x%20-%205%20%3D%207x%20%2B%2050%20%5C%5C%2012x%20-%205%20-%207x%20%3D%207x%20%2B%2050%20-%207x%20%5C%5C%2012x%20-%207x%20-%205%20%3D%2050%20%20%5C%5C%205x%20-%205%20%3D%2050%20%5C%5C%205x%20-%205%20%2B%205%20%3D%2050%20%2B%205%20%5C%5C%205x%20%3D%2055%20%5C%5C%20x%20%3D%2011)
and check:

Answer:
10
Step-by-step explanation:
Here we go!
Slope Formula:
![\frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7By%7D%5E%7B2%7D%20-%20%20%7By%7D%5E%7B1%7D%20%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20-%20%20%7Bx%7D%5E%7B1%7D%20%7D%20)
What we know: (-4, -52) and (-1, -22)
Plug in the numbers!
![\frac{ - 52 - ( - 22)}{ - 4 - ( - 1)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%2052%20-%20%28%20-%2022%29%7D%7B%20-%204%20-%20%28%20-%201%29%7D%20)
Fix it!
![\frac{ - 52 + 22}{ - 4 + 1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%2052%20%2B%2022%7D%7B%20-%204%20%2B%201%7D%20)
Add
![\frac{ - 30}{ - 3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%2030%7D%7B%20-%203%7D%20)
Divide
(negative divided by a negative is a positive!!)
Slope is 10
Hope this helps!
