Hi
Income tax is progressive
So with 50 000 we have :
0.02*3000 + 0.03 ( 5000 -3001) + 0.05 ( 17 000-5001) + 0.0575 ( 50 000 - 17 001) = 60+ 59.97+599.95 + 1897.44 = 2617.36
tax is = 2617.36
Perimeter of a rectangle = length + length + width + width
= 2length + 2width
= 2(35) + 2width
= 70 + 2width
70 + 2width = 84
2width = 14
width = 14/2
= 7cm
The expression is a 3rd-degree polynomial with 4 terms.
Given
The polynomial is;

<h3>What is polynomial?</h3>
A polynomial is an expression consisting of coefficients and variables which are also known as indeterminates.
The highest degree exponent term in a polynomial is known as its degree.
Then,
The total power of the exponent is 3.
The highest degree exponent is 3 then, the expression is a 3rd-degree polynomial with 4 terms.
Hence, the expression is a 3rd-degree polynomial with 4 terms.
