The values of the coefficients a, b and c in the equation is -2, 1 and -1 respectively.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.
Given the polynomial:
-2x³ - 7x² + 3x - 4
Simplifying:
= -(2x² - x + 1)(x + 4)
Hence:
-2x³ - 7x² + 3x - 4 = (-2x² + x - 1)(x + 4)
(x + 4)(ax² + bx + c) = −2x³ − 7x² + 3x − 4
The values of the coefficients a, b and c in the equation is -2, 1 and -1 respectively.

Answer:
x = 9.7
Step-by-step explanation:
Reference angle (θ) = 68°
Opposite = 24
Adjacent = x
Apply, the trigonometric function, TOA which is:
![tan (/theta) = \frac{Opp}{Adj}](https://tex.z-dn.net/?f=%20tan%20%28%2Ftheta%29%20%3D%20%5Cfrac%7BOpp%7D%7BAdj%7D%20)
Plug in the values
![tan 68 = \frac{24}{x}](https://tex.z-dn.net/?f=%20tan%2068%20%3D%20%5Cfrac%7B24%7D%7Bx%7D%20)
Multiply both sides by x
![x*tan 68 = 24](https://tex.z-dn.net/?f=%20x%2Atan%2068%20%3D%2024%20)
Divide both sides by tan 68
![x = \frac{24}{tan 68}](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cfrac%7B24%7D%7Btan%2068%7D%20)
x = 9.69662942
x = 9.7 (nearest tenth)
