Answer:
x = 1/2
Step-by-step explanation:
(x + 2)2 + (9 - 3)2 = 4
2x + 4 + 18 - 6 = 4
2x + 16 = 4
2x = 4/16
2x = 1/4
x = 1/4/2
x = 2/4
x = 1/2
In this case, the answer is very simple.
A term is a part not separated by the signs + or - .
In this expression, we have 3 terms.
The answer is: false.
Morse code is essentially the same as binary. That is, there are two "digits", a dot or a dash.
There are 26 letters in the English alphabet. Clearly, we can't just use one dot or dash, since that could only encode 2 letters at the most. We can't use two symbols because that could only encode 4 letters at the most. Similarly, 3 symbols means

letters at most.
We have to select the smallest power of 2 that exceeds or is equal to 26. In this case,

, so we would have to use up to 5 symbols to encode each letter in the alphabet.
So 2 popcorn = $5×2= $10
And 2 soda. =$2.50×2=$ 5
Add $10+$5=$15.... Judy spent $15 from $30
Hoping this will help.
