2 expressions equivalent to (x-6) • (x-3)
Answer:
x^2 + -9 x + 18 = (x - 9) x + 18 = (x - 6) (x - 3) all three are alternanate forms.
Step-by-step explanation:
Expand the following:
(x - 6) (x - 3)
Hint: | Multiply x - 6 and x - 3 together using FOIL.
(x - 6) (x - 3) = (x) (x) + (x) (-3) + (-6) (x) + (-6) (-3):
x x - 3 x - 6 x - 6 (-3)
Hint: | Combine products of like terms.
x x = x^2:
x^2 - 3 x - 6 x - 6 (-3)
Hint: | Multiply -6 and -3 together.
-6 (-3) = 18:
x^2 - 3 x - 6 x + 18
Hint: | Group like terms in x^2 - 3 x - 6 x + 18.
Grouping like terms, x^2 - 3 x - 6 x + 18 = x^2 + (-3 x - 6 x) + 18:
x^2 + (-3 x - 6 x) + 18
Hint: | Combine like terms in -3 x - 6 x.
-3 x - 6 x = -9 x:
Answer: x^2 + -9 x + 18 = (x - 9) x + 18 =(x - 6) (x - 3)

what is (9/8)^3x+12=1
The solution for the expression is x = -4.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To solve for x in the equation
(9/8)^(3x+12) = 1
we can take the natural logarithm of both sides and use the properties of logarithms to simplify.
ln[(9/8)^(3x+12)] = ln(1)
(3x+12) ln(9/8) = 0 (since ln(1) = 0)
3x + 12 = 0 (since ln(9/8) ≠ 0)
3x = -12
x = -4
Therefore,
The solution is x = -4.

Charlotte drove 304 miles in 8 hours. If she continued at the same rate, how long would it take to travel 190 miles?
The time to travel 190 miles will be 5 hour.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Charlotte drove 304 miles in 8 hours.
And, She continued at the same rate.
Now,
Since, Charlotte drove 304 miles in 8 hours.
Hence, The speed is,
Speed = Distance / time
= 304 / 8
= 38 miles / h
So, For travel 190 miles at same rate;
Time = Distance / Speed
= 190 / 38
= 5 hour
Thus, The time to travel 190 miles will be 5 hour.

At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Answer:
x = 2y --------(1)
75x + 250y = 800 ---------(2)
Step-by-step explanation:
Let the number of chicken wings be x
And the number of sliders be y
x = 2y --------(1)
75x + 250y = 800 ---------(2)
The system of equation is x = 2y and 75x + 250y = 800.

Answer:
1,700 MG
Step-by-step explanation:
1, 360 / 2 = 40% of the daily amount since 20% is taken from the beans.

only sum of an even integer and an odd integer is an odd integer
x is even and y is odd so 2x is even and ±2y is even and x+y is odd
1 is odd and 2 is even which means:
2x±2y is even,
x+y + 1 is even
x-2y is even
