The first number is the sum of 23 and x, and the second number is 18 less than two times the first number. Which of the following functions represents the product of these two numbers?Opions are:
A.
P(x) = 2x^2 + 74x + 644
B.
P(x) = 2x^2 + 28x - 414
C.
P(x) = 2x^2 + 102x + 1,288
D.
P(x) = 2x^2 + 110x + 1,472
Answers
Answer:
It's B.
Step-by-step explanation:
First is x + 23 and second is 2x - 18.
So the product is
(x + 23)(2x - 18)
= 2x^2 - 18x + 46x - 414
= 2x^2 + 28x - 414
