That is negative since the elevator is decreasing. If the elevator was going up, it would be positive.
<span> 3x^2 − 6x = 24
</span>3x^2 − 6x - 24 = 0
3(x^2 - 2x - 8) = 0
3(x - 4)(x + 2) = 0
x - 4 = 0; x = 4
x + 2 =0; x = -2

<span>C) x = −2, x = 4</span>
Answer:
36
Step-by-step explanation:
From the diagram, the following is true;
AY = YB = 7
BZ = ZC = 6
XC = XA = 5
perimeter of the triangle is the sum of all the sides
Hence ;
Perimeter = AY+YB+BZ+ZC+XC+XA
Perimeter of the triangle = 7+7+6+6+5+5
Perimeter of the triangle = 36
hence the perimeter of the triangle is 36
Anything between 91 degrees and 179 degrees. You can pick any between these two.
let the greatest number be a and remainder be x. And let the whole number result of the division be b, c and d. So we have
ab + x = 2447............(1)
ac + x = 3118...............(2)
ad + x = 6168.............(3)
Subtracting (2) - (1) gives:-
ac - ab = 671
a(c - b) =671
Now 671 = 61 * 11 so 61 could be the value of a
Checking:- 2447 / 61 = 40 remainder 7 , 3118 / 61 = 51 remainder 7
and 6168 / 61 = 101 remainder 7
Answer 61
