Answer:
162 ft^2
Step-by-step explanation:
18 * 18 = 324
324/2 = 162
The area of the patio is 162 square feet
The value of x from the given equation is -4/3
<h3>Factorization</h3>
Given the quadratic equation x^2 – 3x – 4 = x^2 – 6x + 8
x^2 – 3x – 4 - x^2 + 6x - 8 = 0
-3x + 6x - 4 + 8 = 0
3x + 4 = 0
- Subtrcat 4 from both sides
3x + 4 - 4 = 0 - 4
3x = -4
3x/3 = -4/3
x = -4/3
Hence the value of x from the given equation is -4/3

The correct simplification of 8x2(5x 2x2 − 3) is 
<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).


Rearranging the above expression in descending order of power, we get:

-5x = - 7 because -6x plus x is -5x and use elimination to get rid of the -3y so you end up with -5x = -7
