Answer:22.6796
Step-by-step explanation:
for an approximate result, divide the mass value by 2.205
Judging by the question at hand I generated this equation.
x+y=12
x=2y
I begin this question by plugging in the x=2y into the equation for x.
So the new equation should be 3y=12. I then divide the entire equation by 3 to get y=4.
Next I plug y=4 into the equation, the new equation should be x+4=12. I then subtract 4 from both sides to get x=8.
The two numbers are :
x=8 y=4
The surface area would be 520. the equation for this is A=2(wl+hl+hw)
Try this solution:if given (1;0;0;10); (0;1;0;2) and (0;0;1;4), then the requirement system of equations is:
