It may be easier to start from
.. a(x +3)(x -1) = 0
.. a(x^2 +2x -3) = 0
The quadratic
.. ax^2 +bx +c = 0 will have solutions -3 and 1 for ...
.. a ≠ 0
.. b = 2a
.. c = -3a
Answer:
x≈20.23
Step-by-step explanation:
x≈20.23
I think the answer is:
F^-1(x)= 1/(x+3)^2
Inverse mean the opposite or reverse
Hope this makes sense! :)
The correct answer is Option c which is the cubic expression is 4x³ − 3x² − 2x + 11
The correct question is as given below:-
Need help ASAP. Choose the expression that represents a cubic expression.
a. 2x + 11
b . −3x² − 2x + 11
c . 4x³ − 3x² − 2x + 11
d . 5x⁴ + 4x³ − 3x² − 2x + 11
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The polynomial having a degree of three is called the cubic polynomial which means that the maximum power of the polynomial will be three and the solutions will also be three.
Here in the option, we can see that the maximum power of the polynomial is three and it will have a maximum of three solutions.
The third-degree expression will be:-
E = 4x³ − 3x² − 2x + 11
Therefore the correct answer is Option c which is the cubic expression is 4x³ − 3x² − 2x + 11

I = PRT....and we are looking for T....so lets re-arrange this...
I / PR = T
I = 4485
R = 11.5% = 0.115
P = 6500
now we sub and solve
I / PR = T
4485 / (6500 * 0.115) = T
4485 / 747.5 = T
6 = T <=== so ur answer is 6 years
