How do you solve this equation, 5s^2-14s-3=0

1 answer:

7 0

It's a quadratic equation. Solve it through factorisation.

5s^2 - 14s - 3 = 0
(5s + 1)(s - 3) = 0

5s + 1 = 0
or
s - 3 = 0

Therefore

s = -1/5
or
s = 3

Please helppp!! Find the missing side . Round to the nearest tenth

olga nikolaevna [1]

Answer:

7. 7.8

Step-by-step explanation:

We can use Tan of this angle to find the missing side (in this case, the side adjacent to the angle measuring 57°)

Tan A = (opposite side)/(adjacent side)

Tan 57° = 12/x

solve for x

x(Tan 57°) = 12

x = 12/(Tan 57°)

x = 7.8 (rounded to the nearest tenth)
