The cube less the square of a number is twice the number. If x is a positive integer, what is its value
1 answer:
Answer:
2
Step-by-step explanation:
let 'x' = number
x³ - x² = 2x
x³- x² - 2x = 0
x(x² - x - 2) = 0
x(x - 2)(x + 1) = 0
x = -1, 0, 2
the only positive solution is the number 2

3x + 10 + 2x -60 + 3x +23 +2x - 13 = 360
10x -40 = 360
10x - 40 +40 = 360 +40
10x = 400
10x/10 = 400/10
x = 40
3x+10 = 3(40)+10 = 130°
2X-60 = 2(40) -60 = 20°
3X+23 = 3(40)+23 = 143°
2x-13 = 2(40)-13 = 67°
