Explicación paso a paso:
Dadas las siguientes ecuaciones;
a) x²-x =0
x² = 0+x
x² = x
x = 1
b) -x²+12x = 0
-x² = -12x
x² = 12x
x = 12
c) 3x² - 9x = 0
Suma 9x a ambos lados
3x²-9x+9x = 0+9x
3x² = 9x
3x = 9
x = 9/3
x = 3
d) x²-2x-3 = 0
x²-3x+x-3 = 0
x(x-3)+1(x-3) = 0
(x+1)(x-3) = 0
x+1 = 0 y x-3 = 0
x = -1 y 3
Pretty sure kL is also 8 since it’s a quadrilateral
I think its 8m/h or somethan but idrk. Like it doesnt specify how long it took him the run the 2 hours so idrk. Or it would be 2m/d + 6m/h with d=day
The perimeter is 17 the area is 160
Given that she slides at a rate of 8m/s and that she was 5 m of the ground after 3 seconds, the number of seconds it takes her to reach the ground from the current position is given by:
Therefore, the number of seconds it takes her to slide to the ground from the top is given by:
