Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.

x and 133 sit on the the same straight line with MO in common. Therefore they are supplementary which means that the add to 180o.
Equation
x + 133 = 180
Solution
Subtract 133 from both sides
x + 133 = 180
x + 133 - 133 = 180 - 133
x = 47 degrees.
Answer
x = 47
From the given scenario above, the value of the car after n years is given by the equation,
V(n) = V₁(1 - d)^n
Where V(n) is the value after n years, V₁ is the original value, d is the depreciation rate and n is the number of years. Substituting the known values,
V(n) = ($25,750)(1 - 0.2)^5
= $8,437.76
Thus, the answer is the second choice.
