4b² + 8b + 3 = 0
4b² + 2b + 6b + 3 = 0
2b(2b + 1) + 3(2b + 1) = 0
(2b + 3)(2b + 1) = 0
b = -1/2 or b = -3/2
Answer:
AD=DC
Step-by-step explanation:
I just took the test, and it said that this is the correct answer.
There are 5 cards less than nine that are prime, so there is a 5/9 chance of picking the first one prime. The second one would be 4/8 or 1/2, because you have removed a card from the deck. You multiply them together to get: 5/18.
Hope this helps!
First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

Using this, we can multiply the 7 out to the
and 3. This gives us:

Now, let's solve for
:



We can see that there is one solution for this equation because
is equal to one definite value after solving. Thus, our answer is A, one solution.
