The three numbers are x, y, z
The sum of the three numbers = x + y + z = 24
Let the first number = x
The second number is five times the first number = y = (x + 5)
The third number is twice as much as the second number = z = 2y = 2(x + 5)
The sum of these numbers = 24
x + y + z = 24
Substituting the values of y and z in terms of x
x + (x + 5) + 2(x + 5) = 24
x + x + 5 + 2x + 10 = 24
4x + 15 = 24
4x = 24 - 15
4x = 9
x = 9 ÷ 4
x = 2.25
Therefore,
x = 2.25
y = (x + 5) = 2.25 + 5 = 7.25
z = 2(x + 5) = 2(2.25 + 5) = 2 x 7.25 = 14.5
Sum of the three numbers = x + y + z = 2.25 + 7.25 + 14.5 = 24

What is the question??????
Answer:
B) 110.92 u²
Step-by-step explanation:
to find the surface area, find the area of each side and add them together.
here are all 6 sides:
4.5 * 6.8
4.5 * 6.8
4.5 * 2.2
4.5 * 2.2
2.2 * 6.8
2.2 * 6.8
4.5 * 6.8 = 30.6
4.5 * 6.8 = 30.6
4.5 * 2.2 = 9.9
4.5 * 2.2 = 9.9
2.2 * 6.8 = 14.96
2.2 * 6.8 = 14.96
30.6 + 30.6 + 9.9 + 9.9 + 14.96 + 14.96
110.92
