Answer:
Diameter of circle while measuring vertically=3.5 cm
Diameter of circle while measuring Horizontally=3.6 cm
As you have not written by which instrument from geometry box you have measured the length of diameter.
1. By Scale i.e ruler 2. By Divider Or 3. By mere Observation i.e by comparing length
1.If you have done measurement by simply observation there are maximum possibility of having error.
2. Then if you have measured these lengths by scale or ruler there is very less chances of getting error in measurement of length because sometimes divison in scale varies i.e if a point lies between 4.5 to 4.6 we can't say exactly whether it is 4.5 or 4.6.
3. So it is better to compare line segments by Divider.There is no chances of getting error.
Most probably you have measured Diameter by ruler, Due to that you have faced the problem.

Length=2(x-1)
Width=5
Area=length*width = (2(x-1))(5) = (2x-2)(5) = 10x-10

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:
6x-2x+4 = 4x+4
4(x-1) = 4x+4
30
The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:
4(n+3)-(3+n) = 4n+12-3-n = 3n+9
31
The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.
2(2n-1) = (2)(2n)+(2)(-1)=4n-2

5(g+14)=(5)(g)+(5)(14)=5g+70
The expressions aren't equal as 5(g+14) equates to 5g+70 and 5g+70≠5g+14.
Answer:
a)
<u>The angle formed by intersecting chords is half of the sum of the intercepted arcs:</u>
- 1/2(mST + mPR) = m∠PUR
- 1.2(74° + mPR) = 77°
- 74° + mPR = 2*77°
- mPR = 154° - 74°
- mPR = 80°
b)
<u>The angle formed by two tangents is the half of the difference of the intercepted arcs:</u>
- m∠PSR = 1/2(mPTR - mPR)
- m∠PSR = 1/2(247° - (360° - 247°))
- m∠PSR = 247° - 180°
- m∠PSR = 67°
THE ANSWER IS TRUE IF THEY CROSS PATHS WITH EACH OTHER THAN YES
Well 16 is 8 spaces away so is 0 and so is 24
