The congruent sides of an isosceles triangle are the two sides that are equal in length. These two sides are opposite the equal angles of the triangle. The third side, called the base, is not equal in length to the other two sides.
One meter is equal to 0.001 kilometers.
Pi is a mathematical constant that is approximately equal to 3.14159. It is the ratio of a circle's circumference to its diameter.
21 out of 35 is equal to a grade of 60% when converted to a percentage.
1908 minus 1776 is equal to 132.
(-5xy):(-xy)=
The sum of xy times 3 is equal to 3(xy).
This equation does not equal a number, but it can be factorised. x2-xy-20y2=(x-5y)(x+4y)
That is irrelevant, there is not possible way y=xy, and there is no possible way xy=x.
It equals XY.
xy=70000 x+y=550 Solve.
xy - xy = 0
xy + xy = 2xy
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
2 to the power of -2 is equal to 1/4.x to the power of -y is equal to 1/xy.
XY
It is an expression in the form of: xy+7
