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

A rectangular water tank contains 1440 litres of water. If its length is 120cm and breadth is 80cm, find the height of the water level in the tank.(1 litre=1000cm cube.)
Answers
Answer:
Answer is 150cm
Step-by-step explanation:
Here
l = 120cm
B = 80cm
Rectangular tank contain 1440l of water
As as we know 1l = 1000cm^3
So 1440l = 1440000cm^3
Here,
volume of tank( volume of water) = l *b* h
or, 1440000cm^3= 120cm*80cm* h
or, 1440000cm^3= 9600cm^2* h
h = 150cm
volume of tank( volume of water) = l *b* h
or, 1440000cm^3= 120cm*80cm* h
or, 1440000cm^3= 9600cm^2* h
h = 150cm

Henry spends $50.00 on lunch, $12.00 on a cap and spends $6.00 on bananas. Hicks spend $120.00 on clothes and $15 on a cap. Henry borrowed money from Hicks to buy his items. In other words, Hicks paid for Henry. Lucky for Hicks he had a discount coupon for 10% off his lunch. Hicks bank account has a balance of $225.
A. How much will the purchase cost him
b. What would Hick’s bank balance be after all the debts were paid?
Answers
Answer:
The purchase will cost him $158.
Hick's bank balance would be $67 after all the debts were paid.
Step-by-step explanation:
10% of $50= $5.
$120.00 + $15.00 + $12.00 + $6.00 + 5.00= $158
$225 - $158 = $67

4. Which of the following values of x is not in the domain of f (x) = log; (10-2x)?
Answers
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).
