X²-9x=36
minus 36 both sides
x²-9x-36=0
what 2 numbers multiply to -36 and add to -9
-12 and 3
(x-12)(x+3)=0
set to zero
x-12=0
x=12
x+3=0
x=-3
the number is either -3 or 12
If (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
A point is an abstraction to point a location or vertex (intersection of lines). It has no size. Consequently it does not have shape or color or any physical characteristic.
Then the answer is all of the above.
Apply Pythagoras:
length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)
There are infinite equivalent fraction can be obtained just multiple by any number to both numerator and denominator and you will find equivalent fraction !
as 42/16, 63/24 etc
