My understanding is that when the power is a negative number, move it to the denominator and change it to positive.
In this case, the base is y, the power is -3
y^(-3)=1/(y^3)
Area = 2,520m^2
(47+65)/2 = 56
56x45 = 2,520
Answer:
x = 3
y = 18
Step-by-step explanation:
you replace y with 6x
x + 6x = 21
combine like terms
7x = 21
divide both sides by seven
x = 3
then you plyg 3 into the other equation
y = 6(3)
y= 18
We need to construct the perpendicular bisectors of at least two of the three sides.
The perpendicular bisector is the locus of points that ensures equal distance between any point on the line and the two ends of the segment.
The intersection of the two or three (congruent) perpendicular bisectors is the centre of the circumcircle.
