Answer:
25x² - 16
Step-by-step explanation:
Given
(5x + 4)(5x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 4) + 4(5x - 4) ← distribute parenthesis
= 25x² - 20x + 20x - 16 ← collect like terms
= 25x² - 16

Answer:
0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of grabbing a nickel:
19 nickels out of 17+10+19+23 = 69 coins, so:

Probability of grabbing a penny, considering the first coin grabbed was a nickel:
17 pennies out of 68 coins. So

What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny?

0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
