The value of a from the equation is -63.
Here we have to find the value of a.
Given data:
The equation is = x³ + 8x² + ax -2
The equation is divisible by x -1
So we have:
x -1 = 0
x = 1
Now putting the value in the equation we get the remainder as o because the equation is divisible by x -1.
So;
1³ + 8² + a(1) - 2 = 0
63 + a = 0
a = -63
Therefore we get the value of a as -63.

Answer:
1/9
Step-by-step explanation:
x^-2
We know that a^-2 = 1/ a^2
1/x^2
Let x = -3
1/ (-3)^2
1/9
Let X describes the sales
350.25+0.12x=800.5
Now solve for x
0.12x=800.5-350.25
0.12x=450.25
X=450.25÷0.12
X=3,752.08
the sales necessary for the salesperson to earn at least $800.50 in one week is 3,752.08
