The surface area is 565.4ft² and the volume is 1,017.8ft³
Hope this helps :)
If you want me to show you how I got it just let me know
Should be 59.490 just because if you have to round the tenth and the hundredth together
The answer is graph number 2
9x - 2y = 11 ... (i)
5x - 2y = 15 ... (ii)
Subtracting equation (ii) from (i) we get;
4x + 0 = -4
4x=-4 , x = -1
Replacing x = -1 in equation (i) we get;
9(-1) - 2y = 11
-9 - 2y = 11
-2y = 20
y = 20 ÷ -2 = -10
The solution to the system of equations is (-1,-10).
