Surface area = 17*(sqrt(1155) + 19)
h^2 = 19^2 - 17^2/4
=> h = sqrt(4*19^2 - 17^2)/2 = sqrt(1155)/2
Surface area = 4(1/2*h*17) + 17*19 = 17(sqrt(1155) + 19)
1/2(x + 4) = -12
1/2x + 2 = -12
1/2x = -10
x = -20
Answer:
32x - 24y - 5
Step-by-step explanation:
That's the answer that I got on the question
Answer:
y=1
x=7/4
Step-by-step explanation:
4x + 5y = 12
3x + 4y = 9.25
4x + 5y = 12
12x + 16y =37
-12x -15 y =-36
12x + 16y =37
y=1
x=7/4
