Answer:
A. 2y = 22
Step-by-step explanation:
You are basically combining like terms. Look at the equation and subtract from top to bottom.
You will subtract 5x and 5x, 4y and 2y, and 25 and 3.
Now you have 0 + 2y = 22.
Removing the 0 (because it is worth nothing), you will be left with 2y = 22 which corresponds to A.
Given that Pythagorean Theorum is
A^2 + B^2 = C^2, you need to do the opposite.
To find for A^2, you need to:
Subtract B^2 from C^2. This creates the equation of:
C^2 - B^2 = A^2. This works because A^2 + B^2 is C^2, so the opposite must work.
Now if you're looking for A and not A^2, you need to subtract B^2 from C^2 and then square root the difference.
I hope this helps!

Either:
- He didn't measure from the end of the first paper strip to the end of the last.
- The paper strips were of different sizes
A radian is defined as the angle in a unit circle that gives an arc length of one. A unit circle is a circle with a radius of exactly one that is centered at the origin. Because both radians and degrees are based on the circle, 360 degrees is equal to 2pi radians.
