The friend is wrong - According to the Pythagorean Theorm, if c is the hypotenuse and a and b are opposite sides then c^{2} = a^{2} + b^{2}
if c=65 inches, a=16 inches and b = 63 inches, then
65^{2} =16 ^{2} + 63^{2}
right hand side of the equation = 256 + 3969 = 4225
left hand side of the equation = 65^{2}= 4225
So we see, left hand side = right hand side
Hence the theorm is proved.
Answer:
n=3
Step-by-step explanation:
you have 2n+7=6n-5
start with subtracting 2n from both sides giving you 7=4n-5
now take the -5 and add 5 to both sides, giving you 12=4n
now divide both sides by 4, now giving you 3=n
the variable has to be on the left every time you finish your work living with n=3
52 (if id means is and not imaginary number)
