Answer:
The width is: 11
The length is: 2
Step-by-step explanation:
The width is 5 feet longer than 3 times the length so
If the length is 2: 2 x 3 times = 6 plus the five = 11
The area of a rectangle is a = the width x the lenght
So 2 x 11 = 22 that is the area.

a is a negative odd number
choose two words from the list which describe a^2
Negative
Positive
Odd
Even
Answer:
even
Step-by-step explanation:
because a is not and odd number its even
The requried two words that describe A² are "Odd" and "Positive".
What are odd numbers?Odd numbers are integers that cannot be divided evenly by 2, which means they have a remainder of 1 when divided by 2. They can be represented as 2n + 1, where n is an integer. Examples of odd numbers include 1, 3, 5, 7, 9, and so on. The opposite of odd numbers are even numbers, which can be divided evenly by 2.
The square of any negative or positive number is always positive. Thus, the first two options "Negative" and "Positive" do not apply to A². As for "Even", it describes a number that is divisible by 2, while "Odd" describes a number that is not divisible by 2. Since A is an odd number, A² will also be odd, as it is the product of an odd number multiplied by itself.
Therefore, the two words that describe A² are "Odd" and "Positive".

1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
2. Consider the quadratic relation y = 2x^2 + 6x – 80. a) Factor this equation by:
1. Determining the greatest common factor (GCF).
2. Factoring the equation using common factoring.
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
Answer:
Step-by-step explanation:
1.Consider the quadratic relation y = x^2 – 6x – 16.
a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
[y = x^2 – 6x – 16 : Two numbers when multiplied = -16, but when added = -6, would be: -8 and 2. [-8+2 = -6, and -8*2 = -16] This would lead to (x+2)(x-8) as the two factors.
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
(x+2)=0; x= -2
(x-8)=0; x = 8
2. Consider the quadratic relation y = 2x^2 + 6x – 80.
a) Factor this equation by:
1. Determining the greatest common factor (GCF).
The GCF is 2: 2*(x^2 + 3x - 40)
2. Factoring the equation using common factoring.
2*(x^2 + 3x - 40): Two numbers that when multiplied = -40, but added = 3, would be 8 and -5. So we can factor:
2*(x + 8)(x - 5)
3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).
2*(x + 8)(x - 5)
b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.
0 = (x + 8) and 0=(x - 5); x = -8, and x=5

Does 3(2k-5)=6(k-4)+9 have no solution of many solutions
Answer:
infinite (many)
Step-by-step explanation:
3(2k-5)=6(k-4)+9
6k-15=6k-15
since they are the same on both sides of the equal side any solution for x would work.
The equation 3(2k - 5) = 6(k - 4) + 9 has many solutions.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
3(2k - 5) = 6(k - 4) + 9
6k - 15 = 6k - 24 + 9
6k - 15 = 6k - 15
Both sides of the equation are the same.
This means,
The equation has many solutions.
Thus,
The expression has many solutions.

28. Katrina buys a 64-ft roll of fencing to
make a rectangular play area for her dogs.
Use 2(1 + w) = 64 to write a function for the
length, given the width. Graph the function.
What is a reasonable domain for the situation?
Explain.
Answer:
Step-by-step explanation:
The reasonable domain for the function 2 ( l + w ) = 64 is:
5, 10, 15, 20, and 25
The graph of the function 2 ( l + w ) = 64 is given below.
What is a function?A function is defined as a relation between a set of inputs having one output each.
We have,
A function of the perimeter of a rectangle:
2 ( l + w ) = 64
Here,
l = length and w = width
We need to find the value of length and width such that the perimeter of the rectangle is 64.
Now,
2 ( l + w ) = 64
l + w = 32
This means the combined measure of length and width must give us 32.
We need to write as a function for length where width is given.
We can assume the width to be: 5, 10, 15, 20, and 25.
Now,
l + 5 = 32
l = 27
l + 10 = 32
l = 22
l + 15 = 32
l = 17
l + 20 = 32
l = 12
l + 25 = 32
l = 7
We consider,
Width = 5, 10, 15, 20, and 25 to be the domain.
Length = 27, 22, 17, 12, and 7 to be the range.
We consider width values as the x-axis and length values as the y-axis.
The graph is given below.
Thus the reasonable domain for the situation given above is:
5, 10, 15, 20, and 25
The graph of the function 2 ( l + w ) = 64 is given below.

I will give BRAINLIEST to the person that solves this.
If Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag then Springer gets 5/12 of the bag of dog food.
What is Fraction?A fraction represents a part of a whole.
Given that Amelie has three dogs, Max, Jasmine, And Springer.
Max gets 1/4 of the bag, Jasmine gets 1/3 of the bag, and Springer gets the rest.
We have to find the fraction of the bag dose Springer get
Let's first add up the portions of food that Max and Jasmine get.
Max's portion = 1/4
Jasmine's portion = 1/3
The total of their portions is:
1/4 + 1/3 = 3/12 + 4/12 = 7/12
This means that Springer gets the remaining portion of the bag:
1 - 7/12 = 5/12
Therefore, Springer gets 5/12 of the bag of dog food.
