Answer:
x, x+2, x+4
(x+2)^2 - 4(x) = 6(x + 4) + 7
x^2 + 4x + 4 - 4x = 6x + 24 + 7
x^2 - 6x - 27 = 0
x = 9 (∨ x = -3)
The three numbers are
9, 11, 13
but it could be also
-3, -1, 1
84 (nearest whole number)
Step-by-step explanation:
If x = 10,
Longest leg = (7 x 10) + 4 = 74
Shortest leg = 4 x 10 = 40
Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse of a right triangle):
⇒ 74² + 40² = c²
⇒ 7076 = c²
⇒ c = √7076 = 84.11896...
⇒ hypotenuse = 84 (nearest whole number)
66.138679
1 ton = 907.185
60,000/907.185 = 66.138679
