Plug in 2 and 4 for every instance of x in the function g(x).
g(x) = 0.023x³ + 0.4x² − 2.1x + 8.3
g(2) = 0.023(2)³ + 0.4(2)² − 2.1(2) + 8.3 = 5.884
g(4) = 0.023(4)³ + 0.4(4)² − 2.1(4) + 8.3 = 7.772
answer: 5.884 and 7.772
That’s what u got I don’t know if there’s another answer
The answer is d i hope this helps even though you prob wont look

2.1a - 0.4b - 1.2 is the correct answer
Thee diagonal of the rectangle is 13.86 cm long.
<h3>What is the length of the diagonal of rectangle?</h3>
We are given that;
Width of a rectangle is 9 less than twice its length. Thus, if length is L, then;
W = 2L - 9
Area formula for a rectangle is;
A = Length * Width
We are given area of rectangle = 96 cm²
Thus;
L(2L - 9) = 96
2L² - 9L = 96
2L² - 9L - 96 = 0
Using online quadratic equation calculator gives;
L = 9.53 cm
Thus;
W = 2(9.53) - 9
W = 19.06 - 9
W = 10.06 cm
The diagonal of the triangle will be gotten from Pythagoras theorem;
D = √(9.53² + 10.06²)
D = √192.0245
D = 13.86 cm
Thus, we conclude that the diagonal of the rectangle is 13.86 cm long.
