In short, if the denominator is a decimal or a fraction and you have an integer in the numerator, the numerator gets blown up.
so if you divide by 1/2, the numerator blows up to twice as large, if you divide by 1/5, to five times as large, if you divide by 1/3... well, let's see,

why is that? well, you're dividing, and so is saying "how many times 1/3 goes into 2"?
well, 1/3 + 1/3 + 1/3 = 3/3 or 1, so in 1 whole, the fraction goes there 3 times, so in 2 wholes, it'll be 6 times.
Answer:
7
Step-by-step explanation:
Trial and error. Start with 1 and go to 9
Annual interest rate is 225
Biased is like the resuls are not representative of the whole, you asked a group strongly for a certain think
like if you wanted to see how many people want to keep the gym, a biased example would be if you went to the gym becasuse they are all exercising and like exercising, therefor want the gym to stay

A. not random, these people are picked (she could pick 5 of her friends)
B. random so not biased, but more spread than A
C. also random
A is llikely biased
(2x + 7)(4x -3)
= (2x)(4x) + (2x)(-3) + (7)(4x) + (7)(-3)
= 8x^2 - 6x + 28x - 21
= 8x^2 + 22x - 21 (Answer D)
