Which polynomials are prime? Check all that apply. 15x ^ 2 + 10x - 9x + 7 20x ^ 2 - 12x + 30x - 18 6x ^ 3 + 14x ^ 2 - 12x - 28 8x ^ 3 + 20x ^ 2 + 3x + 12 11x ^ 4 + 4x ^ 2 - 6x ^ 2 - 16
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

The area of the backyard is 1470 feet squared. If the width is 35 ft then what is the length of the backyard?
Answer:
42
Step-by-step explanation:
to find area, we use the formula length times width. in this given question the area is already given. the inverse operation of multiplication is division, so you divide 1470 by 35 and end up with 42
4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?
Answer:
its choice 3) 5
Step-by-step explanation:
We want to see which of the given values of x is not in the domain of f(x) = log(10 - 2x).
The correct option is (3); x = 5.
The domain is defined as the possible inputs of a given function f(x), in this particular case, we have:
f(x) = log(10 - 2x).
Remember that the logarithmic function is only defined for positive arguments, so the values of x that are NOT in the domain of f(x), are these x values such that:
10 - 2x ≤ 0
Solving it for x we have:
10 ≤ 2x
10/2 ≤ x
5 ≤ x
So any value of x equal to or larger than 5 is not in the domain of the given functions, and of the shown options, the only one that is equal or larger than 5 is x = 5, the third option.
So the correct option is the option (3).

Problem 11
Answer: h = 2A/b------------------
Explanation:
We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b
A = (1/2)*b*h
2A = b*h
b*h = 2A
h = 2A/b
================================================
Problem 12
Answers:Equation: (n+2)/5 = 14Solution to that equation: n = 68------------------
Explanation:
The number n is increased by 2 to get n+2
Then we divide by 5 to get (n+2)/5
This is set equal to 14 to get the equation (n+2)/5 = 14
Solving the equation would look like this
(n+2)/5 = 14
n+2 = 5*14 .... multiply both sides by 5
n+2 = 70
n = 70-2 .... subtract 2 from both sides
n = 68
================================================
Problem 13
Answer: Not a solution------------------
Explanation:
We'll replace every copy of x with -3 and simplify
-2x + 5 > 13
-2*(-3) + 5 > 13
6 + 5 > 13
11 > 13
The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.
Therefore, x = -3 is not a solution.
