Answer:

$A * B = \left[\begin{array}{ccc}10&-6\\8&5\\19&-10\end{array}\right]$

Step-by-step explanation:

Given

$A =\left[\begin{array}{cc}2&-2\\3&4\\4&-3\end{array}\right]$

$B = \left[\begin{array}{cc}4&-1\\-1&2\end{array}\right]$

Required

$AB$

To do this, we simply multiply the rows of A by the column of B;

So, we have:

$A * B = \left[\begin{array}{ccc}2*4 + -2*-1&2*-1+-2*2\\3*4+4*-1&3*-1+4*2\\4*4-3*-1&4*-1-3*2\end{array}\right]$

$A * B = \left[\begin{array}{ccc}10&-6\\8&5\\19&-10\end{array}\right]$

Answer:

LA = 120 sq cm

SA = 132 sq. cm.

Step-by-step explanation:

LA = ph where p = perimeter of the base and h = the height of prism.

Your base is a triangle. The third side = $\sqrt{5^{2} - 3^{2} }$ = $\sqrt{25 - 9} = \sqrt{16} = 4$

Now, the perimeter of the triangle is 3 + 4 + 5 = 12

So, LA = 12(10) = 120 sq cm

The area of the base is the area of a triangle. A = bh/2 = 4(3)/2 = 6

SA = 2B + LA where B is the area of the base

SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.

$- 3x + 18 = 7x$

$7x = - 3x + 18$

Add sides 3x

$+ 3x + 7x = + 3x - 3x + 18$

$10x = 18$
