24(height) cm 3.5(length) cm 13(width) cm find the surface area of the prism

2395 cm²

Step-by-step explanation:

You need to find the area of each side of the prism.

the first side is 3.5x24 which equals 840. there are two of those sides since it's a prism, so multiply by 2. 840x2=1680.

the second side is 13x3.5 which is 45.5. multiply that by 2 for the other side, 45.5x2=91.

repeat for the third side: 24x13=312. 312x2=624.

add all of the sides up to get total surface area. 624+91+1680=2395. :)

Let's solve and find out.

3x - 2y = 4
-6x + 4y = -8

To solve by elimination, multiply the top equation by 2 to cancel out y-terms.

2(3x - 2y = 4)
6x - 4y = 8

Now, add the equations together.

     6x - 4y = 8
   -6x + 4y = -8
+
     0  -  0  =  0

Since we get that 0 = 0, this system has infinitely many solutions. Only graphs that represent the same line have infinitely many solutions, so...

D) There are infinitely many solutions because the equations represent the same line
