Answer:

See below in bold.

Step-by-step explanation:

If we draw a line from the point of intersection to the longest side of the rectangle it will meet it at the midpoint.

The same thing will happen when the line is draw to the shortest side.

So the point of intersection is  1/2 * 7 = 3.5 cm from the longest side and 15/2 = 7.5 cm from the shortest side.

(8m-3n)^2 - (4m+3n)^2​
natulia [17]

Answer:

48m^2-72mn

Step-by-step explanation:

We need to solve (8m-3n)^2 - (4m+3n)^2

We know that,

(a+b)^2=a^2+b^2+2ab\\\\(a-b)^2=a^2+b^2-2ab

Using the above formula,

(8m-3n)^2 - (4m+3n)^2=(8m)^2+(3n)^2-2(8m)(3n)-[(4m)^2+(3n)^2+2(4m)(3n)]\\\\=64m^2+9n^2-48mn-(16m^2+9n^2+24mn)\\\\=64m^2+9n^2-48mn-16m^2-9n^2-24mn\\\\=48m^2-48mn-24mn\\\\=48m^2-72mn

So, the final answer is 48m^2-72mn.
