Step-by-step explanation:

I will answer this question with the attached square pyramid

From the attached pyramid, we have:

So, the base area is:

The dimension of each of the 4 triangles is:

So, the area of 4 triangles is:

So, the surface area is:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
