the answers are -12x^2 and 4x^2y. hopefully it helps and i just got it right.
15a is non-exponential because the variable is not in the exponent
Instead, this is a polynomial function. It can also be called a power function as power functions are in the form a*x^b where 'a' and 'b' are fixed numbers.
Because this is an expression, you cannot solve for a value of x.
3x + 96
We can factor a 3 out of this to simplify it further.
3(x + 32) is the simplified form of the given expression.
Given:
The selling price of a ratio set = 72.00
Profit percent = 8%
To find:
The cost price for the radio set.
Solution:
Let x be the cost price for the radio set.
Radio set is sold at 8% profit.



The selling price of a ratio set is 72.00.




Therefore, the cost price for the radio set is 67.
