Answer:
Step-by-step explanation:
(x^2+8x+8)+(-10x^2+5x) = (x^2-10x^2) + (8x+5x) + 8
= -x^2 +13x + 8
I think the first one is UW and the second maybe UX

awwww this is so sweet of you! you see this is the type of people we need in the world, kind people like you just wanting to help, thats why I answer questions on brainly not for the points and popularity but to help people out, thank you! <33333
This is going to take a while. First, set up equations for both Jaidee and Eugene. Jaidee's equation is
s represents the cost of the small box of tangerines and
represents the cost of the large box of tangerines. Eugene's equation is
. Next, I'm going to solve the equations through elimination. Multiply -2 by the first equation and multiply 5 by the second equation.
Do the same for the second equation.
. Then add
This gives you
. Next divide on both sides
this will give you
. So you know what
is. Next, plug in
to
which looks like this
. Solve 10s+500=600
= 10s+500-500=600-500
=10s=100
= 10s/10=100/10
= s=10 . So each box of small tangerines costs $10 and each box of large tangerines cost $20.
Answer:
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>
