Answer:

± 5.59

Step-by-step explanation:

We already know the distance and the acceleration, but we're looking for the time.

D = 1/2at²

50 = 1/2 · 3.2t²

50 · 2 = 1/2 · 2 · 3.2t²

100 = 3.2t²

t = ± 5.59

5.59 · 3.2² = 100

The perimeter of a triangle is 7 a − 11 b . If two of its sides are 2 a + b and a − 9 b , what is the third side?
Genrish500 [490]

Answer:

To find the missing side we need to calculate the sum of the two given sides and then subtract that from the perimeter.

7a - 11b - (2a + b + a - 9b)

= 7a - 11b - (3a - 8b)

= 7a - 3a - 11b + 8b

= 4a - 3b
