Select the polynomial that is a perfect square trinomial.
cestrela7 [59]
The answer is <span>16x2 − 8x + 1
</span>
To be a perfect square trinomial, the rule must be used:
(a - b)² = a² - 2ab + b²

Let's check all choices
A. a = 7x, b = 4
(7x - 4)² = 49x² - 56x + 16

B. a = 2a, b = 5
(2a - 5)² = 4a² - 20a + 25

C. a = 5b, b = √10
(5b - √10)² = 25b² - 10√10 b + 10

D. a = 4x, b = 1
(4x - 1)² = 16x² - 8x + 1

You toss a coin a randomly selecte a number from 0 to 9. What is the probability of getting tails and selecting a 9?
In-s [12.5K]
First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.

Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.

To find them combined, multiply:

1/2 * 1/10
1/20
0.05

Hope this helps!
