Since its more than 450000 the nearest 100000 is:

Apparently there's no solution?? i tried solving it, and i also used a special calculator, but no solution came up
The difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
<h2>What is
perfect square trinomial?</h2>
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.
<h3>How to solve this equation?</h3>
(-2m + 5n)^2
(-2m + 5n)(-2m + 5n)
4m^2-10mn-10mn+25n^2
4m^2 - 20mn + 25n^2
Thus, the difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.

So 12/14 =6/7
so we multiply this by 21 to see how many games they will win
6/7 times 21/1=(6*21)/7=(6*3*7)/7=6*3=18
Answer:
Step-by-step explanation:
Given that,
XY//BD and XB=XC
Since, XB = XC, then ∆XBC is an isosceles triangle with angle <B = <C.
A. If an angle occupy the same relative position at each intersection where a straight line crosses two others straight lines. If the two straight lines are parallel, then the corresponding angles are equal.
To check for corresponding angle: look at if the shape form "F" shape and be sure that the lines that form the "F" shape are parallel.
So, to complete the statement,
Angle XBC = 55° because it a corresponding angle to AXY
They form a "F" and XY//BD
B. To find BXC
We know that triangle BXC is an isosceles triangle
The sum of angle in a triangle is 180°
Then,
XBC + BCX + BXC = 180°
Since, ∆XBC is isosceles then, angle <XBC = < BCX = 55°
Then,
XBC + BCX + BXC = 180°
55 + 55 + BXC = 180°
110 + BXC = 180°
BXC = 180° - 110
BXC = 70°
