Mathematics

Answer:

62

Step-by-step explanation:

The side length of each of the three squares is 4 units.  This means the area of each would be 4² = 16 sq. units.  For the three, this means the total area is 16(3) = 48 sq. units.

The area of each triangle is 7 sq. units; this means together the area of the two triangles is 2(7) = 14 sq. units.

Together this makes the surface area of the prism 14+48 = 62 sq. units.

Evaluate the determinant for the following 1 4 4]<br> 5 2 2<br> 1 5 5
Travka [436]

The determinant of given matrix is zero

Step-by-step explanation:

Given matrix is:

\left[\begin{array}{ccc}1&4&4\\5&2&2\\1&5&5\end{array}\right]

The determinant of a 3x3 matrix is calculated by selecting a single row.

We are choosing the first row.

So,

= 1\left|\begin{array}{ccc}2&2\\5&5\\\end{array}\right|-4\left|\begin{array}{ccc}5&2\\1&5\\\end{array}\right|+4\left|\begin{array}{ccc}5&2\\1&5\\\end{array}\right|\\=1(10-10) -4(25-2)+4(25-2)\\=0-4(23)+4(23)\\=-92+92\\=0

The determinant of given matrix is zero
