Answer:
7 ft
Step-by-step explanation:
Let x be the shorter and y be the longer length
x + y = 10
x = 10 - y
4x = 2y - 2
4(10 - y) = 2y - 2
40 - 4y = 2y - 2
6y = 42
y = 7
<u>in</u><u> </u><u>slope</u><u> </u><u>in</u><u>t</u>ercept
y = -5x - 7
point slope form
y + 5x - 7 =0
Hi Larry
x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6
Good luck !
