Answer:
<h2>x = 8</h2>
Step-by-step explanation:
x³ - 3x² + 2x - 336 = 0
Find one factor of the polynomial
That's
x - 8
because when its value is equated to zero substituted into the polynomial will give you zero
Factorize x - 8 out
We have
(x - 8) ( x² + 5x + 42) = 0
x - 8 = 0
x = 8
x² + 5x + 42 = 0
Since the roots of this quadratic equation are complex and are not real numbers
<h3>x = 8</h3>

Answer:
d. 75,595
Step-by-step explanation:
Given the estimated regression equation :
y=550 + 30x1 + 9x2
if number of items made (x) = 2500 ; number of stores stocking the product (x2) = 5
Predicted profit (y) will be :
Substitute the values x1 = 2500 and x2 = 5 into the estimated regression model:
y=550 + 30(2500) + 9(5)
y = 550 + 75000 + 45
y = 75595
Hence, the predicted profit will be 75,595
