Answer:

24 bricks

Step-by-step explanation:

The equation of the bricks per row can be:

b = 60 - 3r

where r = row and b = bricks.

if r = 12:

b = 60 - 3 * 12\\b = 60 - 36\\b = 24

(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.
