Answer:
The the length of the rectangular prism is 6.64 mm
Step-by-step explanation:
knowing the surface area of the rectangular prism is the sum up of all areas of the prisma we have
(20 * 5.9)*2 + (20*X)*2 + (5.9*X)*2 = 733.28
236 + 40X + 34.81X = 733.28
X = 6.64 mm

Answer:
There is one solution
Step-by-step explanation:
2x + y = -1
8x + 3y = -2
Multiply the first equation by -4
-8x -4y = 4
Then add the equations together to eliminate x
-8x -4y = 4
8x + 3y = -2
--------------------
-y = 2
Multiply by -1
y =-2
Now find x
2x+y =-1
2x+-2 =-1
Add 2 to each side
2x-2+2=-1+2
2x=1
Divide by 2
x = 1/2
