You first need to multiply the whole second equation by to. So, your two equations would then be -8x + 5y = -9 and 8x + 6y = -46. You then add the two equations to get 11y = -55. This would mean you get y = -5. Then you substitute -5 for y in the first equation. This would mean it would be -8x -25 = -9. Then you add 25 to both sides to get -8x = 16. Then you divide both sides by -8 to get x = -2.
Area=lw
l=2w
aera=2l^2
72=area
72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units
Answer:
1/600 or 0.00166666 in decimal
Step-by-step explanation:
6*10^-2=1/(6*10^2)=1/(6*100)=1/600
The answer is D. First add 2k, then divide by a, the subtract x, then divide by -1
