Answer:
Step-by-step explanation:
The coefficients of x on each side of the equal sign are different, so the equation is <em>not a tautology</em>. It must have exactly one solution.
Answer:
"because the graphs of the two equations overlap each other"
Step-by-step explanation:
If he graphs both equations on the graphing calculator and it shows only one line this can mean only one thing:
<em>Both linear equations are the same</em>
An example of this is
x+y=2
2x+2x=4
If you simplify the second equation by dividing everything by 2 you get the same equation as the first one
This means the answer would be "because the graphs of the two equations overlap each other"

Step-by-step explanation:
Solution at attachment box
Total surface area of cuboid is = 12x18x2 + 10x12x2 +18x10x2
=432+240+360
=1032
Surface of the 1 cube =2x2x2 = 8
Surface of the all cubes = 8x270 = 2160
