Answer:
4.32
Step-by-step explanation:
if your question was 1.8x2.4 then it is 4.32.
1.8
x2.4
_____
4.32
first you take the 0.8 and multiply it by 0.4 then by 2, then take the 1 and multiply it by 0.4 and 2 after that you should get 4.32 after adding them.
3 - 5n = -22
You're essentially just trying to get "n" isolated, or by itself.
So, in order to do that, we must move anything that doesn't have a variable in it onto the other side of the equal sign.
To do that, we must subtract 3 from both sides.
-5n = -22 - 3
Then, we simplify our equation.
-5n = -25
Then, we have to divide both sides by -5, so that we get the answer for "n."
-5n ÷ -5 = -25 ÷ -5
Simplify this.
n = -5

Answer:
19.7
Step-by-step explanation:
a^2+b^2=c^2
so 18^2+8^2=x^2
324+64=388
x is about 19.7
The answer to the given question is as below:-
Polynomials:-
x³-7x²+9x-5x⁴-20
x⁵-5x⁴+4x³+2x-1
3x²-5x⁴+2x-12
Non-polynomial:-
x⁻5-5x⁻⁴+4x⁻³+2x⁻1-1
<h3>What are polynomials?</h3>
A polynomial is a mathematical equation made up of indeterminates and coefficients and involves only addition, subtraction, multiplication, and non-negative integer exponentiation of variables. The exponents of the polynomials can not be irrational.
So the table will be formed as:-
Polynomials:- Non-polynomial:-
x³-7x²+9x-5x⁴-20 x⁻5-5x⁻⁴+4x⁻³+2x⁻1-1
x⁵-5x⁴+4x³+2x-1
3x²-5x⁴+2x-12
Therefore the polynomials and non-polynomials are shown in the table above.
