Answer:
(2x-3)(2x+3)
Step-by-step explanation:
4x^2-0x-9
(4x^2-9)
(2x)^2 - (3)^2
We recognize that this is the difference of squares a^2 - b^2 = (a-b)(a+b)
(2x-3)(2x+3)

Answer:
a. 0.169x+69.11 > 0.126x+76.74
Step-by-step explanation:
So, there's a lot of talk in the question statement. Of course, it presents some important data... but it's also meant to confuse you.
We can boil it down to the following life expectancies :
Men = 0.169x+69.11
Women = 0.126x+76.74
Then they ask you to write with that men have a greater life expectancy than woman using the models above.
Start by writing the goal:
men > women
Then replace "men" by the model and "women" by the model:
0.169x+69.11 > 0.126x+76.74
And you have your answer.
Answer:
Result is 36.
Step-by-step explanation:
The square trinomial is actually square binomial
m∧2 - 2mn + n∧2 = ( m-n )∧2 = (-2-4)∧2 = (-6)∧2 = 36
Good luck!!!
