AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1
The zeroes (where the line crosses the x-axis, these are also the solutions) and the vertex (the highest or lowest point)
Answer:
530
Step-by-step explanation:
If a credit card advertises an annual interest rate of 23%, then the equivalent monthly interest rate is 1.74%
The annual interest rate = 23%
The credit card interest rate the amount you have to pay to borrow the money from them. The credit card interest rate is usually expressed in yearly rate. This is called annual percentage rate.
The monthly interest rate = 
= 
= 1.0174
Then,
= (1.0174-1) × 100%
Subtract the terms first
= 0.0174 × 100%
Multiply it
= 1.74%
Hence, if a credit card advertises an annual interest rate of 23%, then the equivalent monthly interest rate is 1.74%

(f.g)(1) = 18
Step-by-step explanation:
We are given:
f(x) = x^3+3
g(x) = 2x +4
We need to find (f.g)(1)
Solving (f.g)(1) :

So, (f.g)(1) = 18
