Answer:
15x2+10x-9x+7
8x3+20x2+3x+12
11x4+4x2-6x2-16
Step-by-step explanation:
The prime polynomials are;
⇒ 15x² + 10x – 9x + 7
⇒ 8x³ + 20x² + 3x + 12
⇒ 11x⁴ + 4x² – 6x² – 16
What is an expression?
Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
There are some polynomials.
Now,
Evaluate all options in order to check that the polynomials are prime or not as;
Since, The polynomial is called a prime polynomial if the polynomial has not lower degree factors.
1). 15x² + 10x – 9x + 7
15x² + 10x – 9x + 7 = 5x(3x + 2) - (9x - 7)
Thus, This polynomial can not be factored into lower degree polynomial. Hence, it is a prime polynomial.
2). 20x² - 12x + 30x - 18
20x² - 12x + 30x - 18 = 4x (5x - 3) + 6 (5x - 3)
= (4x + 6) (5x - 3)
Thus, This polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.
3). 6x³ + 14x² - 12x - 28
6x³ + 14x² - 12x - 28 = 2x² (3x + 7) - 4(3x + 7)
= (2x² - 4) (3x + 7)
Thus, This polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.
4). 8x³ + 20x² + 3x + 12
8x³ + 20x² + 3x + 12 = 4x² (2x + 5) + 3 (x + 4)
= (4x² + 3) (2x + 5)
Thus, This polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.
5). 11x⁴ + 4x² – 6x² – 16
11x⁴ + 4x² – 6x² – 16 = x² (11x² + 4) - 2 (x² + 8)
Thus, This polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.
Therefore, The prime polynomials are;
⇒ 15x² + 10x – 9x + 7
⇒ 8x³ + 20x² + 3x + 12
⇒ 11x⁴ + 4x² – 6x² – 16

what is the median in the box plot ? 50 60 70 80 90 100
Answer:Median
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Joe sold a total of 10 baked goods. Each cookie costs $1.25 and each brownie costs $2.50. Joe made $20 at the bake sale. How many cookies did Joe sell?
Answer:
16 cookies
Step-by-step explanation:
20/1.25=16
You take the total cost and divide it by the individule cost
Answer: Joe sold 5 cookies
Step-by-step explanation:
If you do the multipaction you will know that 2.50 x 5 = 12.50 and then you would have 5 more baked goods so then you would multiply 1.50 x 5 which equals 7.5 which when you add together equals a total of 20

Joseph invested $6,700 in an account paying an interest rate of 5.2% compounded
quarterly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $13,950?
Answer:
it will take 14 years approximately
Step-by-step explanation:
To get this, we use the compound interest formula
We have this as:
A = P ( 1 + r/n)^nt
where ;
A is the amount after the stipulated time = 13,950
P
is the amount deposited = 6,700
r is the rate = 5.2% = 5.2/100 = 0.052
n is the number of times interest is compounded yearly = 4 (quarterly is every 3 months)
t is what we want to calculate
13,950 = 6,700 ( 1 + 0.052/4)^4t
2.082 = 1.013^4t
ln 2.082 = 4t ln 1.013
ln 2.082/ln 1.013 = 4t
56.78 = 4t
t = 56.78/4
t = 14 years

A right triangle has a leg that measures 15 ft and the hypotenuse measures 24 ft. What would the
length of the missing leg be to the nearest whole number?
Answer:
x=19
Step-by-step explanation:
First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:
[tex]15^{2} +x^{2}=24^{2}[/tex]
Then you square the numbers that you currently have:
[tex]225+x^{2}=576[/tex]
Then subtract 225 from both sides to isolate the x:
[tex]x^{2} =576-225[/tex]
This gives you the equation:
[tex]x^{2} =351[/tex]
Then take the square root of both sides which gives you:
[tex]x=18.7349939952[/tex]
Then round to the nearest whole number which gives you x=19

c. Write the inequality that is shown on the number line.
Answer:
-3< x ≤ 4
Step-by-step explanation:
There is an open circle at -3, so -3 is not included
There is a closed circle at 4, which means 4 is included
The line is between which means x is between
-3 is less than x which is less than or equal to 4
-3< x ≤ 4
This type of graph is called a segment.
To write the inequality, read the segment from left to right.
We would start with the endpoint on the left which is a -3,
our variable x would be in the middle, and we would finish
things off with the endpoint on the right, which is 4.
Since we have an open dot at -3, we use a less than
sign between the -3 and the x and since we have a closed at 4,
we use a less than or equal to sign between the x and 4.
When representing a segment by reading it from left to right,
you will only use less than or less than or equal to between the parts.
So the solution for the inequality is read {x: -3 < x ≤ 4}.

The area of a rectangle is 56 square yards. Its length is 2 yards more than three times its width. Find its dimensions
The width is 4 and length is 14 yards
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Area of rectangle= 56 square yards.
let the width be x.
So, length = 3x+ 2
So, Area of rectangle= 56 square yards.
length x width = 56
x(3x+2 )= 56
3x² + 2x -56= 0
3x² + -56= 0
3x( x - 4 ) + 14 ( x - 4) = 0
(3x+ 14) (x- 4) = 0
x= 4, -14/3
Hence, the width is 4 and length is 14 yards.
