Ok so first off you need to get rid of the clauses in the equation.
So 4.5 ( -4) becomes -18 and -2.5(3+28) becomes -77.5
-18 + 36 = 202 - 77.5
Now you are going to solve the equation.
18 = 122.5
Hope this helped ;),

Answer:
(-3,0)
Step-by-step explanation:
To find the x-intercept set y to 0,
x^2 + 6x + 9 = 0 Now you have a quadratic equation, so you can solve it
(x + 3)(x + 3 ) = 0
x + 3 = 0
x = -3
The price will be $364: take 90% of 400, which is 36. Subtract 36 from 400.
