Answer:
Step-by-step explanation:
Left hand side is a positive number. Right hand side is positive. The equation should have real roots. (worst case, the root would be complex, but let's not open that can of worm)
Let's start noticing that and then take the square root of both sides, remembering that we need to take a plus or minus sign ( both a and -a squared give the same result!)
The answer is 31.4 I remember doing this
Simplify the expressions #3
a) 6+2y-3+4y
=3+6y
b)16+t-2s+12
=18+t-2s
c)3w-6v+4v-100
=3w-2v-100
d)79t+50-30t-3
=49t+47
all i can do for now

What is your story about It could be the exciting part of your story!
Step-by-step explanation:
The probability of the friend completing the new level in her first try is 22.5%
<h3>What is probability?</h3>
This is a concept that is used to talk about the likelihood or the chances of an event occuring.
For the digit 8, the frequency is 7
For the digit 9, the frequency is 11
The total number of frequencies is given as
10 + 9 + 6+ 7 + 8 + 12 + 4 + 6 + 7 + 11 = 80
7 + 11 = 18
Probability = 18/80
= 0.225 x 100
= 22.5%
