30 POINTS, Im pretty hopeless at this point and i know someone is just gonna rob the points thanks anyways
Allushta [10]

Answer:

\dfrac{ah}{a+h}

Step-by-step explanation:

Consider similar triangles BMC and KMN.

In these triangles,

\dfrac{BC}{KN}=\dfrac{MO}{MP},

where O is the point of intersection of BC and MP.

Note that segment OP has the length the same as the side of the square ABCD. Hence,

\dfrac{BC}{a}=\dfrac{h-BC}{h},\\ \\BC\cdot h=a(h-BC),\\ \\BCh=ah-aBC,\\ \\BC(h+a)=ah,\\ \\BC=\dfrac{ah}{a+h}.

I’m confused how do you solve 378 divided by 6 like I know that it’s it 63 but how do you solve it
KatRina [158]

378 divided by 6 is 63

That is the solution. 63 is the final answer. You could mix it around to make sure and say... 6 times 63 equals 378

But there is no more than 63
