Answer:
Time = 133.3 secs
Step-by-step explanation:
<u><em>Speed = Distance / Time</em></u>
<em>Rearranging the formula</em>
Time = Distance / Speed
Where D = 200 m , S = 1.5 m/s
Time = 200 / 1.5
Time = 133.3 secs
Answer:
x= - 4
Step-by-step explanation:
2 * x^2 + 8 * x = x^2 - 16
2 * x^2 - x^2 + 8 * x + 16 = 0
x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4
(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)
2x^2 + 3x + 4x - 9 = 2x^2 +7x -9
2x^2 + 7x - 9 - x^2 -7x = x^2 -9
The answer is : x^2 - 9
