Answer:
roots are 8 and 11
Step-by-step explanation:
Vieta's theorem tells you the sum of roots in this case* is the opposite of the x-coefficient, so is 19. Their product is the constant term, 88.
It is convenient to search for the roots by considering the factors of 88:
88 = 1·88 = 2·44 = 4·22 = 8·11
Only the latter pair of factors has a sum of 19, so those are the roots we're looking for.
The roots of the equation are 8 and 11.
_____
* If the quadratic is ax²+bx+c with a≠1, then the sum of roots is -b/a, and their product is c/a.
Area of a parallelogram is A = base times height
Area = 15 * 13 = 195
So, your answer is 195 cm squared

Step-by-step explanation:
We want to know "probability that first is vowel AND second is vowel"
In probability theory, "AND" means Multiplication.
<em>Essentially we want to figure out probability of first drawn to be vowel and multiply that with probability second drawn is vowel as well.</em>
<em />
There are 5 vowels and total 12 letters, so
P (vowel) = 5/12
<u>For the second draw, there are STILL 12 letters and 5 vowels (since the first drawn is REPLACED)</u>. Hence, probability of 2nd vowel is the same. So:
P (vowel for 2nd draw) = 5/12
<em>Now we multiply them to get: </em>
