You divide 3 on both sides then you equation is the square root of -4x-4 =4 and you square the number on both sides because u need to do the same things on both sides and you get -4x-4=16 subtract by 4 on boyh sides to get -4x=20 and divide by -4 on both aises to get x=-5
I hope this helped i know this explanation is a bit wonky
Answer:
Step-by-step explanation:
Remark
This is just a matter of adding 2 fractions and reducing the result
Givens
f1 = 3/12
f2 = 1/12
Equation
Answer = f1 + f2
Solution
answer = 3/12 + 1/12
The denominators are the same. The answer will have the same denominator
Answer = (3 + 1)/12
Answer = 4 / 12
The answer has a common factor in both the top and bottom of the fraction (4 is the common factor).
Therefore divide the top and bottom by 4
Answer = 4/4 // 12/4
Answer = 1 / 3
So we want to know what do we need to measure to determine the wavelength of the wave on the image. A wavelength is the distance between peaks of the wave. More generally, the distance on which the wave shape repeats. So on the image we need to measure X to determine the wavelength. So the correct answer is X.
