Answer: she has $20 left now.
Step-by-step explanation:
The total amount of money that Kathryn had yesterday was 105 dollars.
She first spent 1/3 of it at the mall. This means that the amount of money that she spent at the mall is
1/3 × 105 = $35
The amount left after her shopping would be 105 - 35 = $70
Later, she went to the movies and spent 5/7 of what was left after her shopping. This means that the amount of money that she spent at the movies is
5/7 × 70 = $50
The amount that she has left now is
70 - 50 = $20
Given the polynomial of degree 4, this can be written as:
x^4-100
let
x^2=a
thus the expression can be written as:
a^2-100
this is a polynomial of degree 2 also known as quadratic equation.
Hence the answer is:
