<span>The equation is not quadratic in for because it cannot be written as a second degree polynomial</span>
The discount is 60% of regular price, or we can write it as
discount = 60% × regular price
input the numbers
discount = 60% × regular price
discount = 60% × 45
discount = 60/100 × 45
discount = 2,700/100
discount = 27
The answer is $27
9/10(3x+12y+-6z) is the expression, simplified it's:
2.7x+10.8y-5.4z
Hope this helped!
